Daily JavaScript Challenge: Check for Balanced Brackets in a String

Hey fellow developers! 👋 Welcome to today's JavaScript coding challenge. Let's keep those programming skills sharp!

The Challenge

Difficulty: Medium

Topic: Brackets and Parentheses

Description

Write a function that checks if a given string has balanced brackets. The brackets to be checked are: parentheses (), square brackets [], and curly braces {}. A string is considered balanced if every opening bracket has a corresponding and correctly placed closing bracket. The function should return true if the brackets are balanced, otherwise false.

function checkBalancedBrackets(str) {
const stack = [];
const bracketMap = {
')': '(',
']': '[',
'}': '{'
};

for (let char of str) {
    if (['(', '[', '{'].includes(char)) {
        stack.push(char);
    } else if ([')', ']', '}'].includes(char)) {
        if (stack.pop() !== bracketMap[char]) {
            return false;
        }
    }
}

return stack.length === 0;
