JavaScript and Why It’s Important to Your Marketing Strategy

By Raka October 13, 2023

Before we get too far into defining and explaining JavaScript: Yes, we’re going to talk about code. No, we don’t expect you to be inbound marketers and web developers. However, even as a marketer, a basic knowledge of this common programming language can be incredibly useful.

Tell me more

OK, JavaScript is an object-oriented programming language, which means it defines both the data type and the operations or functions that can be applied to that data. The data structure as a whole—data type and functions—then becomes an “object,” sort of like a building block. Developers can then create relationships between objects. Still with us? Good.

JavaScript is also a client-side language, which means the source code is processed by the web browser, not the web server. That means those functions we were talking about before can run without having to communicate with the server.

For example: Say you’ve got a form on a landing page with several required fields. A JavaScript function can be used to check the form to ensure all required fields have been filled out and can produce an error message if something’s missing, without any information actually being passed to the server.

This is sort of the crux of JavaScript’s usefulness for webpages—it allows the page to respond to a user’s actions without loading an entirely new page, and therefore enables developers to create an interactive user experience.

Why JavaScript is important to marketers

As a digital marketer thirsty for knowledge in all things inbound marketing, there’s a good chance you’ve experienced the benefits of JavaScript coding already, even if you didn’t know it.

If you’re a HubSpot user, then JavaScript is what your forms are built in, and any customization should be done by a programmer familiar with JavaScript. If you use tracking code, like Google Analytics, to track users’ actions your website, the snippet of code doing that work is JavaScript.

There are, of course, limitations to what JavaScript can do. Whether you’re working with an in-house programmer, an agency, or a contract developer, it’s important to discuss any major website changes and has realistic expectations of capability and time.

You may not be writing JavaScript as a marketer, but you’re definitely using it. And you’re likely working with someone who is writing in JavaScript, so at the very least, it’s helpful to speak the same language, right?
