Hi Friends 👋,

Welcome To Infinitbility! ❤️

Today, I’m going to show How do I check if a string contains a specific character in Javascript, here I will use the javascript string includes() method to check if a string contains a specific character or not.

What is a includes() method?

The includes() method determines whether an array includes a certain value among its entries, returning true or false as appropriate.

Let’s start the today’s tutorial How do you check if a string contains a specific character in JavaScript?

Let’s understand how we can do it

  1. Create a string variable
  2. Use the includes() method and pass specific character
  3. Console the which string contains a specific character
// Create a string variable
const str = 'Hello world';
const char = 'e';

// Use `includes()` method and pass specific character
// Console the which string contains a specific character
console.log(str.includes(char)); // 👉️ true

if (str.includes(char)) {
  // 👉️ string contains the character
}

The above program is the simplest way to check string contains a specific character or not. let’s check the output.
