What are some common JavaScript coding challenges for interviews?
Common challenges include reversing a string, finding duplicates in an array, and implementing a debounce function.
Can you explain how to implement a debounce function?
Sure! A debounce function limits the rate at which a function can fire. It delays the execution until after a specified wait time.
What is the difference between 'let' and 'var' in JavaScript?
'let' has block scope, while 'var' has function scope. This affects variable accessibility in different contexts.
Can you give me an example of a string reversal challenge?
Certainly! You can reverse a string using the split, reverse, and join methods: str.split('').reverse().join('').
