Strict Equality Operators

Snippet

In JavaScript, always prefer '===' (strict equality) over '==' (loose equality). Strict equality checks if both the value and the type are the same.

snippet.js
javascript
const price = 10;
const input = '10';
 
console.log(price === input); // false
console.log(price == input);  // true

Breakdown

price === input

Compares value and type (number vs string), resulting in false.

price == input

Converts types before comparing, making them 'equal', which can lead to bugs.
