How to create a pipe function in JavaScript?
The pipe function needs to accept an arbitrary number of arguments (operations). This is made possible with rest parameter. According to MDN rest parameter, represents an indefinite number of arguments as an array. Utilizing our current pipe function and rest parameter syntax, a new pipe function can be produced that accepts n number of functions.
What’s the difference between single pipe and single operator?
The difference is that the | (single pipe) is bitwise or operator and when it can also be used in condition design. for eg. In above code snippet ” | ” will check every part of condition while ” || ” will check in sequence starting from first.

Why does pipe return Buckethead in JavaScript?
Since we used rest parameters, pipe allows any number of functions to be used. It’ll just loop and call each one. On the next debugger, we’re inside reduce. This is where currentValue is passed to currentFunction and returned. We see the result is ‘Buckethead’ because currentFunction returns the .name property of any object.
