RegEx for extracting the last combination of numbers from a paragraph

Question

RegEx for extracting the last combination of numbers from a paragraph

E.g.:

“My ID is 112243 and my phone number is 0987654321. Thanks you.”

So I want to extract the phone number here which is the last combo of digits.

Answer 1

You can use this regex,

\d+(?=\D*$)

Here, \d+ selects one or more number and this positive lookahead (?=\D*$) ensures that if at all anything is present further ahead before end of string then it is not a digit (by using \D* before $).

Regex Demo

JS Code demo,

const s = 'My ID is 112243 and my phone number is 0987654321. Thanks you.'

console.log(s.match(/\d+(?=\D*$)/))
