`String.prototype.endsWith()`

Determines whether a string ends with the given substring.

Since ES2015 Spec ↗

Syntax

str.endsWith(searchString, endPosition)

Name	Type	Required	Description
`searchString`	`string`	Yes	The substring to test for at the end.
`endPosition`	`number`	No	Treat the string as if it were only this many characters long. Defaults to string length.

boolean — true if the string ends with the substring; otherwise false.

console.log('image.png'.endsWith('.png'));

Output

true

console.log('hello world'.endsWith('hello', 5));

Output

true

Case-sensitive. Throws TypeError if given a regular expression. The endPosition argument effectively checks a prefix of the string.
