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
