What is Mocha & Chai?

Jordan Davis — Mon, 27 Feb 2023 04:13:20 +0000

When it comes to testing in JavaScript, two tools that are often used together are Mocha and Chai.
Mocha is a testing framework, while Chai is an assertion library.
They work excellently together to help do tons of different software development cycles.

Mocha
Mocha is a rich JavaScript testing framework that makes asynchronous testing simple.
It runs on Node.js and in the browser and allows you to write tests in various styles, whether BDD, TDD, or Unit-style.
Mocha has a robust API for running tests, hooking into test execution, and generating reports.
Mocha makes it easy to write tests that are easy to read and maintain and integrates well with other testing tools and libraries.

Chai
Chai is an assertion library that provides a clean, readable syntax for writing assertions in JavaScript.
It is commonly paired with Mocha but can be used with any testing framework.
Chai provides a variety of assertion styles, including should, expect, and assert, so you have plenty of choices.
Chai's API is designed to be easy to use, and it provides a range of built-in assertions for testing lots of JavaScript datatypes and structures.

What it's like using Mocha & Chai together
When Mocha and Chai are used together, they give you many options for testing JavaScript applications.
Mocha gives the structure and control flow for running tests, while Chai provides the assertions necessary for testing the application's behavior.
You must install both libraries using npm and then require them in your testing code to use them together.

Setup and Testing

First, we'd set up a new directory inside our terminal. We can run this command:

mkdir blog, then cd blog

To initialize a new Node.js project, you can run the following command in the terminal:

npm init

To install Mocha and Chai as development dependencies, you can run the following command in the terminal:

npm install Mocha Chai --save-dev

Then we create a new directory at the root of the project. This one will contain our function code to test:

mkdir src

We will create a function to test :

function myFunction(str) {
  return str.length === 4;
}

Here we export myFunction
module.exports = myFunction;

We still need a test directory to hold our test file:

mkdir test 
touch testMyFunction.js

Inside testMyFunction, we write our test code:

const assert = require('chai').assert;
const myFunction = require('../src/myFunction');

describe('myFunction', function() {
  it('should return true if the input string has length 4', function() {
    const result = myFunction('abcd');
    assert.isTrue(result);
  });

  it('should return false if the input string has length other than 4', function() {
    const result = myFunction('abc');
    assert.isFalse(result);
  });
});

To check if this is working, we then need to go to update the "test" script inside our package.json file to run Mocha:

"scripts": {
    "test": "mocha test/testMyFunction.js"
  },

Now with that, we can run this command in our to check our test:

npm test

We should get an output like this:

Conclusion
Now we're done! We used some terminal shortcuts, created a couple of folders and files, installed the dynamic duo Mocha & Chai, and made a passing test!
If you're new to testing in JavaScript, Mocha and Chai are great places to start. They're easy to learn and use, and it's an excellent start to building more complex testing suits!

Keyboard Shortcuts to Make Your Developer Life Easier!

Jordan Davis — Mon, 13 Feb 2023 02:52:59 +0000

Keyboard shortcuts are essential for efficiency in your day-to-day developer lifestyle! There are so many shortcuts that you might be thinking, "Man, there are too many to learn. How will I ever remember them all?!" You might also be wondering, "Why should I learn these things? Are they really that important?"

Yes - they are! Whether you're a software developer or a fry cook, it's important to be an efficient & proper worker. This is the difference between knowledge and wisdom - not only learning to do what you do, but also learning how to do it efficiently. Trust me, the more you code, the more useful (and easier) these shortcuts will be.

In this blog, I'll supply you both Mac & Windows versions of shortcuts so that whatever operating system you're using, you'll have the tools you need to code!

Copy, Paste, and Cut

These three are your 'bread & butter' of your day-to-day coding use, whether you have to copy a portion of code to share, cut incorrect code, or paste the correct syntax.

Mac

Copy: ⌘(cmd) + C 
Paste: ⌘(cmd) + V 
Cut: ⌘(cmd) + X

Windows

Copy: Ctrl + C 
Paste: Ctrl + V
Cut: Ctrl + X

Undo

Undo is truly a life saver! I can't tell you how many times I've typed variable names incorrectly or accidentally deleted a whole part of my code. It happens! 99.9% percent of the time, I utilize the undo shortcut instead of backspace/delete!

Mac

Undo: ⌘(cmd) + Z

Windows

Undo: Ctrl + Z

Save

No one likes grabbing their mouse, clicking "file," clicking "save as," etc. In your coding domain, the save shortcut is your best friend, especially since you should be running your git commands as often as possible.

Mac

Save: ⌘(cmd) + S

Windows

Save: Ctrl + S

Comment Out a Section

When navigating through code and trying to debug, commenting out a line or section is essential (or, if you're like me, you comment out a block to redo!)

Mac

Comment: ⌘(cmd) + /

Windows

Comment: Ctrl + /

Search Within a File

You can use this shortcut in 2 different ways:

You can search in the sidebar/directory (in VSCode) for a specific word or name and it'll show you all instances of that word.
You can do it inside the document and pair it with our next shortcut to edit all instances of the word.

Mac

Directory: ⌘(cmd) + Shift +  F
Document: ⌘(cmd)+  F

Windows

Directory: Ctrl + Shift + F
Document: Ctrl + F

Edit All Instances of a Word

As said previously, this shortcut can help you edit all instances of a word. You can re-type a different word in every instance of that previous word.

Mac

⌥(Option) + return

Windows

ALT + ENTER

Take a Screenshot

Taking a screenshot is used for many different purposes. One of the number one situations I've used this shorting is to send code snippets to the help-desk. It's necessary to be able to share errors when you're stuck!
Mac

Screenshot: ⌘(cmd) + shift + 5(Mojave or later) || 4 & 3

Windows

Screenshot: PrtScn

Highlight a Whole Line

Personally, I'm still learning how to implement these last shortcuts, but highlighting a whole line can be useful when you have to redo a line or code/pseudo code.
Mac

Highlight: ⌘(cmd) + shift + Right Arrow
Highlight: ⌘(cmd) + shift + Left Arrow

Windows

Shift + Down Arrow

Highlight a Single Letter or More

While highlighting a whole line can be helpful, this shortcut may be more useful. Usually when we're coding, we don't want to erase strings and other containers. This shortcut will allow you to select a portion of a line.

Mac & Windows

Highlight: Shift + any arrow

While it may take a while to get the hang of these shortcuts, they will allow you to code without ever having to take your hands off the keyboard! They may not seem like a big deal, but shortcuts will be an asset to you on your journey to becoming a software developer. Although these are only a few of the shortcuts available, I hope they make your day-to-day coding experience better!

Higher Order Functions

Jordan Davis — Thu, 12 Jan 2023 18:54:49 +0000

There are tons of different ways to code but an efficient way to code is with 'Higher Order Functions'.

These are some of the methods you may have heard of
--> Array.prototype.map, Array.prototype.filter and
Array.prototype.reduce are some of the Higher-Order functions that are built into JS!

Let's start with the
Array.prototype.map -->
The map() method creates a brand new array by calling the callback function on every element in the array.
map() then will take all of those values and return a brand new array. map() uses 3 parameters for it's callback -->
element, index, array.
EX -->

const array = [1, 2, 3, 4, 5];
const multiplied = array.map(function(element) {
  return element * 2;
});
console.log(multiplied);
This prints - [2, 4, 6, 8, 10]

Next we have the
Array.prototype.filter -->
The filter() method creates a brand new array with the elements that pass the condition by the callback function.
filter() uses 3 parameters for it's callback -->
element, index array.
EX -->

const friends = [
  { name: 'Bailey', age: 24 },
  { name: 'Jordan', age: 23 },
  { name: 'Merlin', age: 30 },
  { name: 'Rachel', age: 26 },
  { name: 'Nico', age: 23},
];
const older = friends.filter(people => people.age >= 24);
console.log(older);
This Prints - [
  { name: 'Bailey', age: 24 },
  { name: 'Merlin', age: 30 },
  { name: 'Rachel', age: 26 }
]

Our last method of discussion is Array.prototype.reduce() -->
The reduce() method calls the callback function on each element in the array and then gives us a single value. reduce() also has an initialValue available the initialValue does this -->

If the initialValue is provided, the accumulator will equal the initialValue and the currentValue will equal the first element in the array.

If no initialValue is provided, the accumulator will equal to the first element in the array and the currentValue will be equal to the second element in the array.

reduce() uses four parameters for its callback --> accumulator, currentValue(or current), currentIndex(or i), array.
EX without initialValue -->

const array = [5, 7, 1, 8, 4];
const sum = array.reduce(function(accumulator, current) {
  return accumulator + current;
});

console.log(sum);
This prints - 25

EX with initialValue -->

const sum2 = array.reduce(function(accumulator, current) {
  return accumulator + current;
}, 10); // <-- 10 is the initialValue

console.log(sum2);
This prints - 35

This concludes our into to Higher Order Functions I hope this can be of service to anyone who needs a quick and easy understanding of map(), filter(), and, reduce()!
