Remove zeros from Date string

Question

I have a string with the following format: '01/02/2016' and I am trying to get rid of the leading zeros so that at the end I get '1/2/2016' with regex.

Tried '01/02/2016'.replace(/^0|[^\/]0./, ''); so far, but it only gives me 1/02/2016

Any help is appreciated.

Answer 1

Replace \b0 with empty string. \b represents the border between a word character and a non-word character. In your case, \b0 will match a leading zero.

var d = '01/02/2016'.replace(/\b0/g, '');
console.log(d); // 1/2/2016

var d = '10/30/2020'.replace(/\b0/g, '');
console.log(d); // 10/30/2020 (stays the same)

Answer 2

You can use String.prototype.replace() and regular expression to replace the zero at the binning and the zero before / like this:

var d = '01/02/2016'.replace(/(^|\/)0+/g, '$1');
console.log(d);
