Find characters in a string and add whole word to array when found

Question

var arr = [];
var str='This is mWORDy word docuWORDment';

if (str.indexOf('WORD') > -1) {
  arr.push(Whole word here)
}

This works but I need to push the whole words that contains WORD into the array.

So the result should be this:

arr['mWORDy','docuWORDment'];

How can I do this?

Answer 1

You can split the sentence and use filter to filter the array. Use includes to check if a string contains a certain word.

var str = 'This is mWORDy word docuWORDment';
var arr = str.split(" ").filter(o => o.includes("WORD"));

console.log(arr);

Answer 2

Using String.prototype.match() with a simple regular expression:

const str = 'This is mWORDy word docuWORDment';
const result = str.match(/\w*(WORD)\w*/g);

console.log(result);
