Web Tools #406 - CSS Tools, SVG, Svelte, jQuery

Way back in ES6, a new regular expression flag was added to the ECMAScript specification called the "sticky" flag, represented with a 'y' in the syntax.

This flag is used in conjunction with the lastIndex property of a regular expression instance. This property is an old ECMAScript feature. To understand the sticky flag, let's first consider what lastIndex does.

The lastIndex property more or less keeps track of where a global regex search left off.  The following code shows how you can read the lastIndex property during a global regex search, and how it factors into the search:

The comments explain what's happening but you can try it live in this CodePen. As you can see, lastIndex indicates where to start searching for the next possible match.

That brings us to the "sticky" flag. This new flag tells the search to only take place starting exactly where the lastIndex property is set. Here's an example which includes a line where I define lastIndex:

Try it on CodePen

That's more or less sticky in a nutshell but if you want a more practical discussion of how it can be used, this article might help.
