What is the difference between let and const hoisting in JavaScript?
An example of an AI chatbot conversation about let vs const hoisting in JavaScript.
What is the difference between let and const hoisting in JavaScript?
In JavaScript, both 'let' and 'const' are block-scoped, but they behave differently when it comes to hoisting.
Can you explain how hoisting works for let and const?
Sure! Variables declared with 'let' and 'const' are hoisted to the top of their block, but they cannot be accessed until the declaration is encountered.
What happens if I try to use a let or const variable before it's declared?
If you try to use a 'let' or 'const' variable before its declaration, you'll get a ReferenceError due to the 'temporal dead zone'.
Are there any scenarios where I should prefer let over const?
You should use 'let' when you need to reassign a variable, while 'const' is best for variables that won't change.
