How to Replace Periods in Strings Using JavaScript?

Replacing Periods in Strings with JavaScript

In JavaScript, you can replace all occurrences of a dot (.) in a string using the replace() method with a regular expression as the first argument. However, the literal period period (.) matches any character in a regular expression. To avoid this, you need to escape it using a backslash ().

Example:

Consider the following string:

<code class="javascript">var mystring = 'okay.this.is.a.string';</code>

To replace all the dots with spaces, you can use the following code:

<code class="javascript">mystring = mystring.replace(/\./g, ' ');</code>

This will output:

<code class="javascript">"okay this is a string"</code>

Note that the escaped period (.) now matches only periods in the string.
