An example of an AI chatbot conversation about common mistakes with let and const in JavaScript.
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 redeclaring 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.
What happens if I try to redeclare a variable with const?
If you try to redeclare a variable declared with 'const', you'll get a SyntaxError because 'const' does not allow redeclaration.
Are there any scenarios where I should prefer let over const?
Yes, you should use 'let' when you need to reassign a variable, such as in loops or conditional statements.
