Locate individual characters within a string and append the entire word to an array upon discovery

Question

Locate individual characters within a string and append the entire word to an array upon discovery

Given an array and a string, how can we push whole words that contain the word 'WORD' into the array?

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

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

Although the current code works, we aim to modify it so that we achieve this result:

arr['mWORDy','docuWORDment'];

How can we accomplish this task efficiently?

Answer №1

To break up a sentence into individual words and apply filtering to an array, you can utilize the split method along with filter. You can also use the includes method to determine if a string contains a specific word.

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

console.log(arr);

This regular expression can be utilized to identify and extract specific word patterns surrounded by word boundaries, storing them in an array for further processing.

const pattern = /\b([A-Za-z]+WORD[A-Za-z]+)\b/gm;
const str = `This is mWORDy word docuWORDment`;
let m;

let matchedArr = [];

while ((m = pattern.exec(str)) !== null) {
  // Add the matched group to the array
  matchedArr.push(m[1]);
}

console.log(matchedArr);
