Replace a comma with a Dot in JavaScript

Using the replace() method

The best simple way to replace a comma with a dot is using the replace() method. This method allows you to use the regular expression to find out the comma in your string and replace it with a dot. We already have an article on how to use this method. Please read it here

Example:

In this example, we will use replace() method with the g modifier set to loop to all strings and replace all commas with a dot. g in the regular expression is for global search. Please view the code example below to get more information.

var myString = "Hello, I'm LearnShareIT,,,";

// use regular expression with replace() method with g modifier
newString = myString.replace(/,/g, '.')

console.log(newString)

Output

Hello. I'm LearnShareIT...

Using the split() and join() methods

The other way to replace a comma with a dot is by using the split() method to split a string into an array of substrings and then using the join() methods. Join the value of the string in the list and replace commas with a dot separator. The Join() and split() methods are ES1 features. It is fully supported for all browsers.

Split() method

Syntax: string.split(separator, limit)

Parameters:

• separator: a string or regular expression to use for splitting.
• limit: an integer that limits the number of splits. Items after the limits are excluded.

Return value: return value is an array containing the split values.

Join() method

Syntax: string.join(iterable)

Parameters:

• iterable: any iterable object where all the returned values are strings. Default is a comma

Return value: return value is a string that must be specified as the separator.

Example:

In this example, we will use the split() method to split the string on commas into a list, and then we re-join all elements and replace them with a Dot. See the code example below to understand.

var myString = "Hello, I'm LearnShareIT,,,";

// splitting the string on comma by using split() method
parts = myString.split(',');

// and re-join all with Dot
newString = parts.join('.');
console.log(newString)

Output

Hello. I'm LearnShareIT...
