What are the common mistakes when using let and const in JavaScript?

Some common mistakes include using let and const interchangeably, not understanding block scope, and trying to reassign const variables.

Can you explain the difference between let and const?

Sure! 'let' allows you to reassign variables, while 'const' is used for variables that should not be reassigned after their initial value.

What happens if I try to reassign a const variable?

If you try to reassign a const variable, you'll get a TypeError indicating that you cannot assign to a constant variable.

Are there any scenarios where using let is preferred over const?

Yes, use 'let' when you need to change the value of a variable, such as in loops or conditional statements.
