What are some common mistakes JavaScript beginners make?

Some common mistakes include not understanding variable scope, using == instead of ===, and forgetting to declare variables.

Can you explain why using === is better than ==?

Using === checks for both value and type, preventing unexpected type coercion, while == only checks for value.

What about variable scope? Why is it important?

Variable scope determines where a variable can be accessed in your code, which helps avoid conflicts and bugs.

How can I avoid these mistakes as a beginner?

Practice writing clean code, use strict mode, and regularly review your code to catch potential issues early.
