Declarative Data Transformation

Snippet

Chaining higher-order functions like filter and map allows for processing collections in a clean, readable, and declarative way.

snippet.js
javascript
const nums = [1, 2, 3, 4, 5];
const result = nums
  .filter(n => n > 2)
  .map(n => n * 2);

Breakdown

.filter(n => n > 2)

Creates a new array containing only elements greater than 2.

.map(n => n * 2)

Transforms each remaining element by doubling its value.
