What is Javascript?


JavaScript is a widely used programming language that is commonly associated with web development. It is a high-level, interpreted language that can be used on both the client and server sides of web applications. JavaScript was first invented in 1995 by Brendan Eich at Netscape, , taking mere 10 days to write. It was first created as a scripting language for the company’s flagship web browser called Netscape Navigator and was first called LiveScript. It was later changed to JavaScript to be positioned with Java, a language created by their partner, Sun Microsystems. The language’s turning point was in 2008 when Google’s Chrome V8 - a high-performance JavaScript engine - was created. Today, it has become one of the most popular programming languages and can be used everywhere.


JavaScript is primarily used for front-end web development. It allows developers to create dynamic and interactive web pages, by manipulating the HTML and CSS on the client-side. This includes creating animations, form validations, and responsive designs. Additionally, JavaScript can be used to create full-fledged web applications, such as single-page applications (SPAs), that operate entirely within a web browser. Some popular JavaScript frameworks and libraries for front-end development include React, Angular, and Vue.js.

JavaScript can also be used for server-side development, using platforms such as Node.js. This allows developers to create scalable, high-performance web applications that can handle a large volume of requests. Node.js is particularly useful for real-time applications, such as chat applications or online gaming platforms.

JavaScript does not only play a role in web development, but is also used for server applications and AI & machine learning projects. Other uses for Javascript can be seen in creating web applications, web browsers, games, art, smartwatch apps, mobile apps, flying robots, and so much more.


One of the main benefits of JavaScript is its versatility. It can be used for both front-end and back-end development, which allows developers to create full-stack applications without having to switch between different programming languages. Additionally, JavaScript is supported by all modern web browsers, which means that it can be used to create cross-platform web applications that work seamlessly on desktop and mobile devices. It also improves website performance and reduces overhead, as well as provides a rich interface, and optimizes server load.

Another benefit of JavaScript is its flexibility. It is a loosely-typed language, which means that developers do not need to declare variable types before using them. This can lead to faster development times, as well as more concise and readable code.

Finally, JavaScript has a large and active community of developers, which means that there are numerous resources available for learning and troubleshooting. This includes online forums, documentation, and libraries of pre-built code. This makes it easier for developers to create complex applications and solve problems quickly and efficiently.

What is a promise in Javascript?

The Promise is an interesting word, getting the attention of many non-developers. This is more technical than it is “fun”, however, it is an important part to know when learning about JavaScript. The object “Promise” represents the eventual completion or failure of an asynchronous operation and its resulting value. It is unsure when it is created but it is always in one of these three states: pending, fulfilled, and rejected. Developers use it to manage their code easier. Every developer at Dirox can use the promise well in their codes and in fulfilling your business goals. 

Why do I need JavaScript for my website?

JavaScript is used both for client-side and server-side and makes the website interactive. HTML and CSS give structure and style, whereas JavaScript gives interactive elements to the web pages to engage the viewers.

You can do so many things with JavaScript, all of which will improve your website dramatically. JavaScript is among the most popular programming languages, and sometimes it even beats others to be at the top.

At Dirox, our JavaScript developers are always honing their skills with large projects and are ready to join your team to make a difference! Consult with us to get a quote.

What are the disadvantages of JavaScript?

Coins have two sides, and so does JavaScript. As with many coding languages, they can easily face browser issues that interpret the code differently.

Thus, testing the code on various platforms is necessary to have it run smoothly. It is also hard to debug as there are fewer debugging facilities available for JavaScript. And one error, just one, in the code can stop the entire JavaScript from running.

To users, it will look like there is no JavaScript available, however, browsers are typically tolerant of it.

Which languages work with JavaScript?

Since JavaScript is a lightweight, interpreted, object-oriented programming language, it is mostly used to script web pages, meaning it works with HTML & CSS.

However, JavaScript can be used in non-web environments as well. It can be used with, written in, translated to C#, C++, Python, and so many more, which is what gives it the magic to be everywhere in everything! How cool is that!
