I need to enter a "0" in case there's only one digit after the comma, how does replace() work in this situation?

var a = "2x 250,5";

console.log(a.replace(a.split(",")[1], a.split(",")[1] + 0));

//expected result
// 2x 250,50

//Output
//2x 2500,5

You could search for a comma, digit and end of string and add a zero at the end.

var a = "2x 250,0";

console.log(a.replace(/,\d$/, '$&0'));

Split string but replace with another string and get list, x = "HelloWorldHelloYou!" y = x.replace("Hello", "\nHey\n").lstrip("\n").split("\n") print(y) # ['Hey', 'World', 'Hey', 'You!'] This is a rather brute-force� The primitive approach to replace all occurrences is to split the string into chunks by the search string, the join back the string placing the replace string between chunks: string.split(search).join(replaceWith). This approach works, but it’s hacky.

console.log([a.split(','), a.split(',').pop().length===1 ? '0':null].join(''));

  • Your code is replacing the first "0" it finds.
  • a.split(",")[1] -> 0. If you replace 0 with 00 in 2x 250,0 that's what you'd get. Not sure why you expect this to be different. Moreover, if you're splitting already, just use the split value, and join it together, instead of replacing.
  • Do you need 01 or 10 ?

  • This replaces 250,15 with 250,150.
