After doing this practice, you can deliver your project with less effort. So, let’s begin and see all the best practices you need to do!
Practice #1 Maintain Quality of Code using Tools like JSlint and ESLint
ESLint helps you maintain good code quality by identifying and reporting to you if any errors come in your code so that you can immediately improve it and maintain good quality in your project.
Practice #2 Define Variable names properly
You need to define variables appropriately, and to define them, you need to know three fundamentals when naming variables:
1 . The variable name must describe the information and tell specifically in words what the exact meaning of the variable is.
2 . You need to prioritize how easy your code is readable rather than faster written.
3 . You need to adapt standard convention for naming variables so that it’s useful for global decisions.
Defining variables specifically help you to enhance your project speed.
Practice #3 Avoid Global Variables as much as possible
There are various reasons to avoid global variables as much as possible because they’re easy to overwrite in different areas because they’re available everywhere. As we all know, global variables are properties of windows to overwrite things in the window object.
Practice #4 Define a Function per task
Three different ways to define Functions:
- Function Declaration
- Function Expression
- Generator Function
Practice #5 Validate all the data, both incoming and outgoing
- Basic Validation: First, you must check the form to make sure all mandatory fields are filled.
- Data Format Validation: Second, you must check the entered data for the correct value.
