Can you explain block scope?
An example of an AI chatbot conversation about block scope in programming.
Can you explain block scope?
Sure! Block scope refers to the visibility of variables within a specific block of code, like inside curly braces {}.
How does it differ from function scope?
Function scope allows variables to be accessible throughout the entire function, while block scope restricts access to the block.
Can you give me an example of block scope?
Absolutely! In JavaScript, if you declare a variable with 'let' inside a block, it won't be accessible outside that block.
What happens if I use 'var' instead of 'let'?
Using 'var' declares a variable with function scope, meaning it can be accessed outside the block it was declared in.
