What are the best practices for scoping in JavaScript?
An example of an AI chatbot conversation about best practices for scoping in JavaScript.
What are the best practices for scoping in JavaScript?
Some best practices include using 'let' and 'const' for block scoping, avoiding global variables, and using IIFE.
Can you explain why avoiding global variables is important?
Avoiding global variables helps prevent naming conflicts and keeps your code modular and easier to maintain.
What is an IIFE?
An IIFE, or Immediately Invoked Function Expression, is a function that runs as soon as it is defined, creating a new scope.
How does 'let' differ from 'var' in terms of scoping?
'let' has block scope, meaning it's limited to the block it's defined in, while 'var' has function scope, which can lead to unexpected behavior.
