How to strip every character from a string except numeric characters and decimal point

Question

'US $109.90/ea' should become '109.90'

Replace `[^\d.]+` with nothing. – ctwheels Nov 19 '19 at 23:46 — ctwheels, Nov 19 '19 at 23:46

You can replace all characters except number and dot with empty string:

var str = 'US $109.90/ea';
var number = str.replace(/[^\d.]+/g, '');
console.log(number);

No alternation needed. Add `+` quantifier to make it more efficient (like I have in my comment below the question) – ctwheels Nov 20 '19 at 00:02
