An example of JavaScript array traversal method _javascript skills

The example in this article describes the method for JavaScript array traversal. Share to everyone for your reference, specific as follows:

<! DOCTYPE html>  

some: Returns true as long as there is an option in the array that satisfies the condition, returns False if none of the items meet the criteria, and does not iterate over the remaining elements.
every: returns false as long as there is an option in the array that does not meet the condition, and returns true if all items meet the condition.
Filter: Filters the array, which returns the new array, and push the element that satisfies the condition in the original array to the new array
map: Each element in an array executes the callback function once and returns the new element to the new array
ForEach: Executes the callback function once for each element in an array that has no return value

The effect chart is as follows:
