Can you explain the difference between reduce and map in JavaScript?
An example of an AI chatbot conversation about using reduce and map in JavaScript.
Can you explain the difference between reduce and map in JavaScript?
Sure! Both reduce and map are array methods in JavaScript, but they serve different purposes.
What does the map function do?
The map function creates a new array by applying a provided function to each element of the original array.
And what about reduce?
The reduce function executes a reducer function on each element of the array, resulting in a single output value.
Can you give me an example of each?
Of course! For map, you could use it to double each number in an array. For reduce, you could sum all the numbers in an array.
