How to check if Two Strings are Equal in JavaScript


How to check if Two Strings are Equal in JavaScript ?

Answer

To check if two strings are equal in JavaScript, you can use the strict equality operator === or the == operator.



✐ Examples

1 Check Equality using === Operator

In this example,

  1. We create two string variables str1 and str2 with the same value "Hello".
  2. We check if str1 === str2, which will return true if they are equal and have the same type, and false otherwise.
  3. Finally, we log the result to the console.

JavaScript Program

let str1 = "Hello";
let str2 = "Hello";
let result = str1 === str2;
console.log(`Are strings equal? ${result}`);

Output

Are strings equal? true

2 Check Equality using == Operator

In this example,

  1. We create two string variables str1 and str2 with the same value "Hello".
  2. We check if str1 == str2, which will return true if they are equal, even if they are of different types, and false otherwise.
  3. Finally, we log the result to the console.

JavaScript Program

let str1 = "Hello";
let str2 = "Hello";
let result = str1 == str2;
console.log(`Are strings equal? ${result}`);

Output

Are strings equal? true
