Using Pipe-to-Chain Functions in JavaScript

In JavaScript, pipe is a functional programming concept that allows you to chain functions together so that the output of one function becomes the input of the next function. This is similar to how pipes work in the Unix command line, where the output of one command is piped into the input of another command.

Here's an example of using pipe in JavaScript:

javascriptCopyconst add = (a, b) => a + b;
const square = (n) => n * n;
const double = (n) => n * 2;

const result = pipe(
  add,
  square,
  double
)(1, 2);

console.log(result); // Output: 18

In this example, we have three functions: add, square, and double. We want to apply these functions to the numbers 1 and 2 in a specific order: first, add them together, then square the result, and finally double the result.

To achieve this, we use pipe to chain the three functions together. The pipe function takes any number of functions as arguments and returns a new function that applies each function in sequence.

So in our example, we call pipe with add, square, and double as arguments. This returns a new function that takes two arguments (a and b) and applies each function in sequence to those arguments.
