JavaScript Check whether string1 ends with strings2 or not
We are required to write a JavaScript function that takes in two strings, say, string1 and string2 and determines whether the string1 ends with string2 or not.
For example −
"The game is on" Here, "on" should return true
While,
"the game is off" Above, “of" should return false
Let's write the code for this function −
Example
const first = 'The game is on';
const second = ' on';
const endsWith = (first, second) => {
const { length } = second;
const { length: l } = first;
const sub = first.substr(l - length, length);
return sub === second;
};
console.log(endsWith(first, second));
console.log(endsWith(first, ' off'));Output
The output in the console will be −
true false
