What is Javascript?

Take a look at our blog to find out more about Javascript, and why we use it.

What is Javascript?

The simple answer is that JavaScript is a programming language of the web. The more complicated answer is that JavaScript is one of the core aspects of programming: although there are other systems to code with. HTML and CSS join this language as the three main technologies of the web. Initially only being compatible with Client-side coding, it can now work with server-side too without the need for additional plug-ins so it can run.

JavaScript is a cross-platform language. This means that it can work on different computers, with different operating systems. It’s been around for a long time, too. Overtime it’s evolved to become a part of our daily lives as we browse the online world, it is difficult to come across a website that doesn’t feature JavaScript. The code can be written into an HTML page or writing in its own separate document, which the user requests when they click on the link to your site.

Java and JavaScript aren’t the same, despite the similarities in the names. JavaScript is used more commonly with HTML pages whilst Java is a real programming language. Both descended from C and C++ but have improved and gone into different directions respectively.

The scripting language tells the browser what to do. Through these commands, the user can view the site as you intended. For security reasons, it can’t read files on the end-users computer or run programs, making it safer for people browsing the web when they want to view a HTML file.

Why use Java Script?

One reason that JS is so commonly used is because of how powerful it is: you can do a lot with it, on any device or search engine. A great benefit of using JavaScript is that it’s not too much hassle to set up. It’s also the default for typical browsers, which makes it the go-to for amateur and professional website developers. If you are wanting to learn a client-side coding program, this is probably the program for you!
