Parse Search String

Given a search string like (eg. Github Issue Search):

subject: hi bye text: yes no

Parse it:

input:  subject: hi bye text: yes no

key:  subject
value:  hi bye

key:  text
value:  yes no

This repeatedly tries searching the string with this regex: /(\w+):\s?/. I'm pretty sure there's a better way of doing this.

index.js

#!/usr/bin/env node

const re = /(\w+):\s?/g;
const txt = 'subject: hi bye text: yes no';

console.log('input: ', txt);
console.log();

let matches;
const ms = [];

while ((matches = re.exec(txt)) !== null) {
  ms.push(matches);
}

ms.forEach((m, i) => {
  let nextIdx = ms[i + 1] && ms[i + 1].index;
  if (!nextIdx) {
     nextIdx = txt.length; 
  }

  const key = m[1];
  const value = txt.substring(m.index + key.length + 1, nextIdx);
  
  console.log('key: ', key.trim());
  console.log('value: ', value.trim());
  console.log();
});
