Remove Commas From a String in JavaScript

To remove commas from a string in JavaScript the easiest way is to use the JavaScript String replace() method.

someString.replace(/,/g, "");

Here is the code with a simple example:

var commaString = "This, is, a, string, with, commas.";
commaString = commaString.replace(/,/g, "");

console.log(commaString);

#Output:
This is a string with commas.

Notice in the replace method above, that instead of using .replace(",", "") we use replace(/,/g, ""). If we used the expression "," in the replace function, it only replaces the FIRST instance of a comma. Using the regular expression /,/g makes it so we replace ALL instances of a comma in the string.

When using string variables in JavaScript, we can easily perform string manipulation to change the value of the string variables.

One such manipulation is to remove characters from a string variable. We can easily remove commas from a string in JavaScript.

The easiest way to get rid of commas in a string using JavaScript is with the JavaScript String replace() function.

The replace() function takes two arguments: the substring we want to replace, and the replacement substring. In this case, to remove commas, we pass the comma (",") character as the first argument, and an empty string as the second argument.

Below is our example again of how you can remove commas from strings in JavaScript using the replace() function.

var commaString = "This, is, a, string, with, commas.";
commaString = commaString.replace(/,/g, "");

console.log(commaString);

#Output:
This is a string with commas.
