In JavaScript, the startsWith() and endsWith() methods are used to check whether a string starts or ends with a specific substring, respectively. These methods return a boolean value (true or false) based on whether the condition is met or not.

Here's how they work:

startsWith(): This method checks if a string starts with the characters of a specified string.

const str = 'Hello World';
console.log(str.startsWith('Hello')); // true
console.log(str.startsWith('He')); // true
console.log(str.startsWith('hello')); // false (case-sensitive)

endsWith(): This method checks if a string ends with the characters of a specified string.

const str = 'Hello World';
console.log(str.endsWith('World')); // true
console.log(str.endsWith('rld')); // true
console.log(str.endsWith('world')); // false (case-sensitive)
