Why Is There Such A High-Demand In Jobs For Javascript Developers?

It’s no secret that JavaScript is an important language for web development. After all, browsers are one of the most extensively utilised software applications on mobile devices and computers. JavaScript developers implement the front end logic, which defines the way the visual elements of web applications behave. They also connect this with the services which reside on the back end. Back end web developers who are responsible for server side application logic support JavaScript developers. JavaScript developers usually work along with other front end developers who focus on styling and markup. Here are the top skills that all JavaScript developers must have on their CV.

  1. Declaration and Initialisation

Declaration of variables late in the program is not at all a good practice. You should declare all the variable in the beginning of the program, it’s like taking out all your tools before starting a job. Declaration of all variables before getting into the code of you function gives easy access to and understandability of the program. Apart from declaration, it’s best to initialize your variables at the time of creation so that none are left undefined.

  1. Build Specialized Functions

Javascript functions should only focus on a single task that it sets to accomplish. As a developer you should write the function in order to complete that task only. Another important thing is to name the function to match the particular task so that it is easy for you and others in the team to identify the function. A function written in this way is simpler and less extensive and hence easier for others to read and understand. Make sure your function is only working toward one task. In this manner, your Javascript code would have several functions, each dedicated towards one particular task.

  1. Crisp and Concise Code

As a good developer, you should make the Javascript code as crisp and efficient as possible. Look out for instances in your code for identical lines of code and move them into a function. Call the function in places all the instances where those duplicate lines were used before. Make function according to the earlier point of modular of specialised functions. A concise code without any redundant code reduces visual clutter and also aids in debugging.

  1. DOM manipulations

Accessing the DOM (Document Object Model) is important for getting the most out of your program and especially when it comes to complex programs. However, doing so repeatedly can cause visual clutter and might also slow down the program. A better option is to access it once and cache it for later use in a variable, this way you can access that variable instead of accessing the DOM again and again. You make the code visually cleaner and more efficient by accessing the variable in place of.

  1. Avoiding Global Variables

In JavaScript, the scope of a variable decides where in your code can they be defined or accessed. Mainly, there are two type of variables, global and local. Global variables can be defined anywhere in the program and can be accessed outside of the function also, on the other hand, local variables ca only be accessed within the function it is defined.

Also, in Javascript, if a local variable and a global variable share the same name, the local variable would be given priority. It is a good practice to avoid using global variables in your Javascript code as they can accidentally overwrite window variables and hence cause errors.

A lot of global variables in the Javascript code might also slow down your program because unlike local variables which are deleted once the function is completed, global variables are not deleted until the window is closed.

  1. Using Strict Mode

JavaScript is good at getting code to run without throwing errors. This feature can lead to silent errors that. They are passed without correction which is not desired for the execution of the code. To save yourselves for silent errors, opt into Strict Mode. Opting strict mode, silent errors that would previously make it past the compiler now throw errors. It allows you to fine-tune your code. Add the line 'use strict'; either at the top of your script section or before the desired function to opt in strict mode for the particular Javascript code.

The list above consisted of ten useful Javascript tips and tricks that are going to help you write clean, crisp and efficient code as a developer. When it comes to developing real time applications and development, learning how to code is necessary but never sufficient. You should also know how to be efficient while writing a code because the application you produce will be used by millions of people across the world. Another reason to write clean code is that your piece of code will be accessed by other coders and programmers also. We hope that this list of useful Javascript tips and tricks would make you a more proficient Javascript developer.
