JavaScript is a unique programming language that played a big part in developing the World Wide Web as we know it today. It was the brainchild of computer programmer Brandon Eich and was invented in 1995. Eich initially created it for Netscape 2, but it was the ECMA-262 standard by 1997.

The language is still widely used today, powering many websites. But how does it work?

JavaScript 101

When you take a JavaScript online course, you'll first learn that it's a client-side scripting language. Simply put, JavaScript is a programming language that runs inside an Internet browser, AKA a web client.

Some of the latest estimates say that a whopping 97.6 percent of all web pages today have JavaScript code. They use other programming languages, too. However, JavaScript is what makes many complex features possible. Developers use it to create dynamic web content, creating a level of interactivity beyond statically presenting the information. If you see anything that moves, refreshes, or changes, JavaScript is likely working behind the scenes to make it happen!

Developers place JavaScript code inside a web page. Your browser reads and interprets the code to run the designated function whenever you visit the page. That could be something as simple as smooth animations or more complex elements.

The language is often utilized to validate information and data. JavaScript can calculate, manipulate, and validate data. It's a flexible coding language, and developers can use it in many ways. That's why it plays a significant role in modern web browsing to this day.

Is JavaScript Difficult to Learn?

Developers consider JavaScript to be of average difficulty. It can be challenging initially, but a JavaScript online course is a great way to start your development journey. It's one of the first programming languages that students learn, often paving the way to more challenging codes in the future.

Once you get a good grasp of how JavaScript works and what it can do, the possibilities are endless. While it takes time to comprehend fully, JavaScript is considered one of the foundations of coding and will prove helpful no matter where your skills take you.
