Regex match only numbers that are exactly 5 digits long - Javascript

Question

In javascript - I want to extract only the numbers that are exactly 5-digits long.

let example = "The quick brown 22 333 44 55555

In this case, I want it to match and give me and 55555

Edit: I figured it out. Since I want EXACTLY five digits: .match(/(?<!\d)\d{5}(?!\d)/g)

This ensures it's exactly five and no other numbers that exceed it

Where did `12345` and `55555` come from? For one there is no `1` in the example string. — Cary Swoveland, Apr 06 '20 at 21:06

This will do it.

(?<!\d)\d{5}(?!\d)

The regex you're looking for is:

/\d{5}/

An example:

const example = "hello c12345 df444 3444, 55555";

const matches = example.match(/\d{5}/g);

console.log(matches);
// => [ '12345', '55555' ]

"[0-9]{5}"
[0-9] // match any numbers between 0 to 9
{5} // match exactly 5 times
