Trim each 3 words in newline in string (jquery)

Question

i want to trim 3 letter on each newline . but when i do split it only split the first line the other newline already gone. Kindly help. Thank you.

This is the code:

var mytext = '(1x) test0, (2x) test1, (3x) test2';

var formattedString = mytext.replace(/,/g, '\n');

console.log("FORMATTED STRING", formattedString)

const output = formattedString
    .split('', 4)
    .reduce((o, c) => (o.length === 4 ? `${o}${c}` : `${o}${c}`), '')

console.log("SPLIT", output)

Can access the code here:

I want the output like this: "(1x) \n (2x) \n (3x)"

I'd use a regex to start by matching a ), then match non-( characters, and replace with )\n:

var mytext = '(1x) test0, (2x) test1, (3x) test2';
console.log(
  mytext.replace(
    /\)[^\(]+/g,
    ')\n'
  )
  .trim()
);

Depends on the format of the input string, maybe `.match(/\w+(?=,|$)/g).join('\n')` – CertainPerformance Dec 15 '20 at 05:30
is it should be myText.match(/\w+(?=,|$)/g).join('\n') ? sorry again for asking – TechDev Dec 15 '20 at 05:32

Just assign it to something? `const someNewVar = ...` – CertainPerformance Dec 15 '20 at 05:36
yes assign that in a new var but i wanted to remove the (1x)(2x)(3x) – TechDev Dec 15 '20 at 05:37

Yes, the new variable will indeed contain the text without those parentheses – CertainPerformance Dec 15 '20 at 05:38
