What are the common mistakes when using const and let in JavaScript?
An example of an AI chatbot conversation about common mistakes with const and let in JavaScript.
What are the common mistakes when using const and let in JavaScript?
Some common mistakes include trying to reassign a value to a const variable, and not understanding block scope.
Can you explain why I can't reassign a const variable?
Certainly! A const variable is read-only, meaning once it's assigned a value, it cannot be changed or reassigned.
What about let? Are there mistakes associated with it?
Yes, with let, a common mistake is declaring the same variable name in the same block scope, which leads to errors.
How can I avoid these mistakes in my code?
To avoid these mistakes, always use const for variables that won't change, and be mindful of your variable scopes.
