Javascript-从负数字符串中删除前导零

Question

I have this string "00-12.50" and I would like to remove the leading zeros with and replace with a blank space. How do I do that?

My Regex example is not working: strDedAmount.replace(/^[0]*/, ' ')

This example returns " 0-12.50" Thanks

I suppose using the "with callback" version of string.replace(regex, callback) will serve you well

 const str = '00-12.50' const fixed = str.replace(/^0+/, match => ' '.repeat(match.length)) console.log(fixed)
