lodash-es

What is lodash-es?

The lodash-es package is a variant of Lodash, optimized for tree-shaking and ES module syntax. It provides utility functions for common programming tasks, including manipulating arrays, objects, and strings, as well as utilities for functions, logic, and math operations.

What are lodash-es's main functionalities?

Array Manipulation

Lodash-es provides functions to work with arrays, such as map, filter, and reduce, similar to those found in native JavaScript but with additional capabilities and optimizations.

[1, 2, 3].map(n => n * 3)

Object Manipulation

It offers a suite of tools for manipulating objects, such as merging, cloning, and deep property access.

_.assign({ 'a': 1 }, { 'b': 2 }, { 'c': 3 })

String Manipulation

Lodash-es includes methods for string manipulation, such as case conversion, trimming, and splitting strings.

_.kebabCase('Foo Bar')

Function Utilities

The package provides utilities for functions, such as debounce and throttle, which are useful for optimizing performance for actions that should not happen too frequently.

_.debounce(func, [wait=0], [options={}])

Logic Operations

Lodash-es has functions to perform logical operations, such as checking if a value is empty, equal to another, or matches a certain condition.

_.isEmpty({})

Math Operations

It also includes utilities for math operations, such as add, subtract, multiply, and divide, as well as more complex mathematical computations.

_.add(6, 4)

Other packages similar to lodash-es

underscore

Underscore is a similar utility library that offers functions for working with arrays, objects, and functions. It is less modular than lodash-es and does not support tree-shaking.

ramda

Ramda is a functional programming library that emphasizes a more functional and composable approach than lodash-es. It is designed for a functional programming style, which can be more expressive but also has a steeper learning curve.

immutable

Immutable.js provides persistent immutable data structures which can help to avoid mutable state. Unlike lodash-es, it does not provide utility functions for arrays and objects but focuses on providing immutable data structures.
