What does !== mean in javascript
By Tan Lee Published on Dec 18, 2024 133
The `!==` operator in JavaScript is a strict inequality operator. It compares whether two values are not equal in both value and type, returning `true` if they are either not equal or of different types.
Here's an example:
let num1 = 5; let num2 = "5"; console.log(num1 !== num2); // true
In the example above, num1
is a number and num2
is a string.
Even though both have the value 5, the !==
operator returns true
because they are of different types.
