Lodash FP (Functional Programming)

Functional Programming with Lodash FP

Lodash FP is an alternative to Lodash that favors functional programming (FP) practices.

Key Differences

1. Immutability: All methods return new objects/arrays.
2. Auto-curried methods: All methods can be partially applied.
3. Fixed arity: No optional arguments.

Usage

import fp from 'lodash/fp';

const double = fp.map(x => x * 2);
double([1, 2, 3]);
// => [2, 4, 6]

const getNames = fp.map('name');
getNames([{ name: 'john' }, { name: 'jane' }]);
// => ['john', 'jane']

Composition

const transform = fp.flow(
  fp.map(x => x * 2),
  fp.filter(x => x > 5)
);

transform([1, 2, 3, 4]);
// => [6, 8]

Lodash FP can lead to more predictable and easier to reason about code in functional programming paradigms.
