Pipe

Compose functions elegantly with pipe operator

What is Pipe?

Pipe is a function that allows you to compose operations in a left-to-right, top-to-bottom manner. Instead of nesting function calls or creating intermediate variables, pipe lets you express transformations as a readable sequence of steps.

// Instead of this:
const result = c(b(a(value)))

// Use this:
const result = pipe(value, a, b, c)

➡️

Left-to-Right Flow

Read code in the order it executes

📏

No Nesting

Avoid deeply nested function calls

🐛

Easy to Debug

Step through transformations one at a time

🔗

Compose Anything

Chain together any sequence of functions

Pipe in Action

❌ Nested Functions

const result = formatOutput(
  transform(
    validate(
      parseInput(userInput)
    )
  )
)

// Hard to read, inside-out flow
// Difficult to debug
// Adding steps is awkward

✅ Pipe Approach

const result = pipe(
  userInput,
  parseInput,
  validate,
  transform,
  formatOutput
)

// Left-to-right, natural flow
// Easy to read and debug
// Adding steps is simple
