If word ends with Javascript

Question

I need some way to check if a word ends with certain letters. Basically, the user enters a string, which is split into words using:

var res = spanish.split(" ");

After this I need a way to check if any words in the string contain the letters 'est'. Right now I'm accomplishing that using

if (spanish.indexOf("est") !=-1) {

            }

After this, I need a way to check if the word containing 'est' ends with 'oy'. Any ideas?

Answer 1

I would use regex.

> /^.*est.*oy$/.test('fooestoy')
true
> /^.*est.*oy$/.test('fooesto')
false
