What is the difference between for...of and for...in loops in JavaScript?
An example of an AI chatbot conversation about the differences between for...of and for...in loops.
Can you explain the difference between for...of and for...in loops in JavaScript?
Sure! The for...in loop is used to iterate over the keys of an object, while for...of is used for iterating over iterable objects like arrays.
Can you give me an example of each?
Absolutely! For for...in, you might do: for (let key in obj) { console.log(key); }. For for...of, it would be: for (let value of array) { console.log(value); }.
When should I use one over the other?
Use for...in when you need to access object properties, and for...of when you want to work with array elements or other iterable collections.
