JS is a top programming language
that has been used in one form or another for over thirty years. Because of its longevity, there are many resources available for new users, and a lot of existing expertise.
JS has many uses: you can use JS to apply complex elements on a web page — like interactive maps and animated graphics. But programmers use it for many more functions:
- Mobile application
- Virtual reality
- Interactive maps
- Web Applications
- Game Development
JS is an established, high-level language that requires no compilation. This means that JS can be executed as soon as it’s written, without compiling – so, faster prototyping and less headache.
It’s also versatile and you can use JS for pretty much anything thanks to its extra features like libraries that are full of functions.
JS also offers lower overheads because of being well-optimized. Anything created with JS tends to run smoothly on a wide variety of different machines.
A framework makes it much easier and more expedient to build sites. Instead of coding every part of the site completely by yourself, you simply use common website features from the framework.
Here’s an example: you’re making a standard JS photo carousel on a website, so you use code from a framework to give you that feature. Instead of making it from scratch, you can simply make adjustments to the framework.
This allows you more time to code the less common elements of the site that don’t have a simple plug-in fix.
Some examples of popular JS libraries are MooTools, YUI, jQuery, Prototype, and Dojo.
In the past, a developer would often default to using jQuery. But now, relying on external libraries is no longer needed. That’s thanks to the development of the ECMAScript spec – standardized specification of a scripting language developed by Netscape. Modern browsers keep up with it better.
Like every other programming language, JS has advantages and disadvantages.
JS is also a client-side script – this saves the time needed to connect to the server so it speeds up the execution of the program.
- Versatility – JS is capable of both front-end and back-end development
Also, it’s hard for developers to find the problem because the browser doesn’t show any error.
- Security – JS code is viewable to the user and others may use it for malicious reasons.
Java has to be compiled, while JS code gets written in text and only needs to be interpreted.
Java is used to connect legacy enterprise systems to highly dynamic web interfaces, so it’s useful to many major corporations. Brands that use Java include Airbnb (backend development), Google (apps like Web Toolkit and Gmail), and Uber (built on Java).
It’s difficult to program without
At Coding Dojo, we teach MongoDB, Express, React, Node.js, and more technologies to train you to become a JS developer.
There are several ways to learn, and from a number of different sources. You may want an immersive, full-time program
that is normally taught on site (although currently this option is virtual).
On the other hand, an online, part-time bootcamp
may suit your schedule better.
Even the hardest, most complicated lines of JS code can be written one by one. JS can also be tested in the web browser at the same time.
