5 JavaScript Mistakes and How to Fix Them

Forgetting to Declare Variables with let or const:
Omitting let or const when declaring variables leads to the creation of global variables, which can cause unexpected behavior in your code.

Ignoring async/await for Asynchronous Code:
Writing asynchronous code with nested callbacks (callback hell) instead of using async/await, leading to hard-to-read and maintain code.

Not using const for real constant values:
Using let for variables that don't change can lead to accidental reassignment, introducing bugs. Always use const for variables that should remain constant throughout your code.

Neglecting Error Handling:
Not handling errors properly, leading to applications that crash or behave unpredictably when something goes wrong.
