Remove trailing numbers from string js regexp

I am trying to remove the trailing numbers from the string using JavaScript RegExp. Here is the example.

Input          output

string33     => string 
string_34    => string_
str_33_ing44 => str_33_ing
string       => string

Hope above example clears what I am looking for!



You could use this regex to match all the trailing numbers.


Then remove the matched digits with an empty string. \d+ matches one or more digits. $ asserts that we are at the end of a line.

string.replace(/\d+$/, "")

Use .replace():

"string".replace(/\d+$/, '')

A simple demo jsfiddle:
