Finding in string portions of letters with RegEx and JS

Posted on December 2, 2021

Here a simple way to check if a particular chunk of text is present or not in a given string:

// my string
const myText = 'Hello there! How is going?'

// check if 'are' or 'is' presence in string
const check = myText.match(/are|is/mig)

// 'check' will be = null if not present
// 'check' will be = ['is'] if it finds something

So, you can replace what you found with something else, in this case, just strip them out:

var res = myText

check.forEach(s => {
  res = res.replace(s, '')
