In this manner,
Difference Between For and For Each Loop in C# For Loops executes a block of code until an expression returns false while ForEach loop executed a block of code through the items in object collections. For loop can execute with object collections or without any object collections while ForEach loop can execute with object collections only.

The first difference between map () and forEach () is the returning value. The forEach () method returns undefined and map () returns a new array with the transformed elements. Even if they do the same job, the returning value remains different. 2. Ability to chain other methods
