Question

I'm trying to find whatever starts with a word, followed by a ' , and then followed by a word( /\\w'\\w/ ). For example(i'm, it's, what's,there's,John's), Take John's for example, it will match n's . That is perfect, but once that it is matched I want to replace just the ' and not n and s .

Answer 1

You can use capturing group.

([^'])'([^'])
   |     |________ Group 2
   |
   |______________ Group 1

 let arr = [`i'm`, `it's`, `what's`,`there's`,`John's`] arr.forEach(e=>{ e = e.replace(/([^'])'([^'])/g, "$1$2") console.log(e) }) 

• Press Ctrl+f add regex pattern and select .* option.
• In add replace value in the second input box $1$2

Answer 2

Yes use capture groups. Let's assume you want to replace the ' with ""

Match RegExp:

(\w)'(\w)

Replace with "":

$1""$2

Answer 3

Here's an alternative that doesn't use capturing groups, instead using a lookbehind and a lookahead:

 const replaced = "John's it's I'm 'not this'".replace(/(?<=\\w)'(?=\\w)/g, ''); console.log(replaced);
