How do I check if a string contains a specific substring in JavaScript

Question

With the help of code can you tell me How do I check if a string contains a specific substring in JavaScript?

Answer 1

You can use the includes() method, introduced in ECMAScript 6 (ES6).

Using includes():

This method returns true if the substring is found within the string and false otherwise.

const mainString = 'Hello, Edureka!';

const subi = 'Edureka';

console.log(mainString.includes(subi)); // Output: true

In this example, mainString.includes(subi) evaluates to true because 'Edureka' is a substring of 'Hello, Edureka!'. It's important to note that includes() is case-sensitive.
