Replace() with Split() in JavaScript to append 0 if number after comma is a single digit
Let’s say our sample string is −
const a = "250,5";
If the number after “,” is a single digit we have to append a 0 to it,
If the string contains more than one ‘,’, we have to return -1
This can be done simply by combining the split() and replace() functions like this as in the below example −
Example
const a = "250,5";
const roundString = (str) => {
if(str.split(",").length > 2){
return -1;
}
return a.replace(`,${a.split(",")[1]}`, `,${a.split(",")[1]}0`);;
}
console.log(roundString(a));Output
The console output for this code will be −
250,50
