Check whether a string ends with some other string - JavaScript

We are required to write a JavaScript function that takes in two strings say, str1 and str2. The function should determine whether or not str1 ends with str2. Our function should return a boolean on this basis.

Here’s our 1st string −

const str1 = 'this is just an example';

Here’s our 2nd string −

const str2 = 'ample';

Example

Following is the code −

const str1 = 'this is just an example';
const str2 = 'ample';
const endsWith = (str1, str2) => {
   const { length } = str2;
   const { length: l } = str1;
   const sub = str1.substr(l - length, length);
   return sub === str2;
};
console.log(endsWith(str1, 'temple'));
console.log(endsWith(str1, str2));

Output

This will produce the following output in console −

false
true
