Write Easy to Understand Code

Keeping things simple is the best way to get your work done within a short time span. If you don’t want confusing code, then always write in easy and understandable manner.

Are you a web developer or a designer?  This tool will make your life and workflow a lot easier

Writing easy to understand code can help you accelerate your work at a much quicker pace. But most of the developers make mistakes while writing down an accessible code. Let’s take a look at some of the tips that can help you with this:

  • Don’t use shortcuts: Using inappropriate shortcuts could leave you in a troubling situation. Human beings are obviously not capable of understanding minds, and they could make a mistake while reading your shortcut code or function. Therefore, it is recommended to use only relevant shortcuts for your code and functions. Try to pay more attention to your shortcuts.
  • Keep yourself cool and composed. Forget about the number of lines you have coded, the time you are consuming to complete a single line of code, or whether the app works fine or is quite tedious – Don’t take stress at all. Just focus on producing actual code for each of your projects.
  • Try to use normal language – understandable and convenient. The code you write reflects your ideas and perspective on what you are developing. Instead of using complex language, try to mold them like an engaging and captivating story.

 

Clarify the definitions of Class and Function

Starting off a new application or a library is one of the most challenging tasks. It will be better if you note down the definitions of your classes and functions before you begin anything. It will let you manage all your tasks quickly and efficiently.

In fact, you should use simple and clean names for your functions, variables, and clients that can indicate their respective values with ease. By doing this, you will be able to distinguish between a function and a constant – which simplifies the entire development process.

Work on your API to strengthen security

Security is one of the crucial aspects that need to be concerned while developing a site or an app.  Some people think that hiding components from the user with the help of JavaScript is a real security. But this is just a myth.

A real security is determined the way you write and embed code within your site. A well-coded back-end always keeps your site protected from hackers and malicious threats.

In order to avoid this, you need to focus on your API layer because this is a place where you can put robust walls of security. An API checks the authenticity of every element that passes through it and discards suspicious elements accordingly. It never generates information to a user that doesn’t have the permission to access.

So, it will be beneficial if you build a real API that can offer different layers of security.

Strict mode is a great way that can help you in many ways. You can use it to restrict variant of JavaScript. It enhances the proficiency of a developer while programming in a language, without a compiler. It lets you fix code related errors and problems, without any professional assistance.

You can easily set up the script mode by adding the following lines of codes to the JavaScript files.

‘use strict’;

….

}

It is an essential tip that simplifies the process of developing a site or an app. You can maintain the consistency of your work and enhance its usability while programming a site or app.

Let’s explore some tips regarding the consistency:

  • Continue to build and debug an app until it matches your requirements.

getElementsByClassName

getElementsByTagName

querySelector

// most common elements

With the help of these elements, you can select the most suitable ones according to your specifications in any given time. However, it doesn’t matter how you choose the theme. The most common elements for small web pages are querySelectorAll and querySelector.

But how will you deal with a large number of elements which might cross hundred at a time? In such a situation, you will have to use advanced selectors such as getElementByld. It is a very quick selector and is cross-browser compatible as well.
