@dexthefish/lotide v1.0.1

Lotide

A mini clone of the Lodash library.

Purpose

BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by myself, Dex Davis, as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @username/lotide

Require it:

const _ = require('@dexthefish/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• assertArraysEqual(a,b): log a message indicating (in)equality of arrays a,b
• assertEqual(a,b)): log a message indicating (in)equality of primitives a,b
• assertObjectsEqual(a,b): log a message indicating (in)equivalence of objects a,b
• countLetters(s): sort the characters of a string s into bins with counts
• countOnly(a,b): sort the elements of an array a into bins with counts, but only if they can be found somewhere in b
• eqArrays(a,b): return true iff a and b refer to the same array
• eqObjects(a,b): return true iff a and b refer to the same object
• findKey(a,callback): return the first key of a whose value satisfies callback
• findKeyByValue(a,b): return the first key of a whose value equals b
• head(a): return first element of an array
• letterPositions(s): map the unique characters of s to the set of indices at which they occur
• map(a,callback): return a sub-array of a, taking elements iff they satisfy callback
• middle(a): return the middle element(s) of a as an array
• tail(a): return a new array by excluding the first element of a
• takeUntil(a,callback): return a new array by truncating a at the first element which satisfies callback
• without(a,callback): return a new array by excluding the elements of a which satisfy callback
