What is block scope in ES6?
An example of an AI chatbot conversation about block scope in ES6.
What is block scope in ES6?
Block scope in ES6 refers to the visibility of variables declared within a block, such as inside curly braces {}.
Can you give me an example of block scope?
Sure! If you declare a variable using let or const inside a block, it won't be accessible outside that block.
What happens if I use var instead?
Using var declares a variable with function scope, meaning it can be accessed outside the block it was declared in.
Why should I use let or const over var?
Using let or const helps prevent issues related to variable hoisting and scope leakage, making your code cleaner.
