- Declare Variables Properly: Always declare variables using “let” or “const” keywords to prevent the accidental creation of global variables. Also, declare variables at the top of the scope to avoid hoisting.
- Use Object and Array Destructuring: Object and array destructuring is a convenient way of extracting values from objects and arrays. It makes your code more readable and concise.
- Use Template Literals: Template literals allow you to embed expressions and variables inside a string. They are more readable and maintainable than traditional string concatenation.
- Minimize Global Variables: Avoid using global variables as they can cause naming conflicts and make debugging harder. Instead, use closures and modules to encapsulate your code.
- Use “=== “ instead of “==”: Always use strict equality operators “===” and “!==” instead of loose equality operators “== “ and “!=”. This ensures that you compare values and data types correctly.
- Keep your Code Modular: Break your code into small, reusable modules to make it more maintainable and scalable. This also makes testing and debugging easier.
- Use a Linter: Use a linter such as ESLint to catch common coding mistakes and enforce best practices. It can also help you maintain a consistent coding style across your team.
