JavaScript Array Methods map filter reduce

In JavaScript, map, filter, and reduce are higher-order array methods that allow you to manipulate arrays in a functional and declarative way.
map:
The map method creates a new array by applying a function to each element in the original array.
It iterates through each item in the array, applies the provided function to each item, and returns a new array with the results.
This method is useful for transforming data.
filter:
The filter method creates a new array with all elements that pass the test implemented by the provided function.
It iterates through each item in the array and returns a new array containing only the elements for which the provided function returns true.
This method is useful for filtering out unwanted elements.
reduce:
The reduce method applies a function against an accumulator and each element in the array (from left to right) to reduce it to a single value.
It iterates through each item in the array, accumulating a value based on the result of the provided function.
This method is useful for aggregating data into a single value.
