JavaScript, as one of the most widely used programming languages in web development, empowers developers to create dynamic and interactive web applications. However, writing clean and readable code is crucial for the maintainability and scalability of projects. One often overlooked aspect of clean code is variable naming.
In this article, we’ll explore some best practices for naming JavaScript variables that will help you write clearer, more understandable code.
1. Use Descriptive Names
When naming variables, strive for clarity and expressiveness. Variable names should clearly convey their purpose and meaning within the context of your code. Avoid single-letter or cryptic names like x or temp. Instead, opt for descriptive names that provide insight into the data they represent.
