What is the difference between forEach and map in JavaScript?
An example of an AI chatbot conversation about the differences between forEach and map in JavaScript.
Can you explain the difference between forEach and map in JavaScript?
Sure! Both forEach and map are array methods in JavaScript, but they serve different purposes.
What is the main purpose of forEach?
forEach is used to execute a provided function once for each array element, mainly for side effects.
And what about map?
map creates a new array populated with the results of calling a provided function on every element in the calling array.
So, can I use map if I don't need a new array?
It's better to use forEach in that case, as map is intended for transforming data and returning a new array.
