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 me as part of my learnings at Lighthouse Labs.
Usage
Install it:
npm install @cupokyle/lotide
Require it:
const _ = require('@cupokyle/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertEqual(actual, expected)
: asserts whether two values are identical. -
eqArrays(array1, array2)
: returns true if two arrays are identical. -
assertArraysEqual(actual, expected)
: asserts whether two arrays are identical. -
eqObjects(object1, object2)
: returns true if two objects are identical. -
assertObjectsEqual(actual, expected)
: asserts whether two objects are identical. -
countLetters(string)
: takes in a string and outputs an object containing a numeric value for how many times each letter appeared in the string. -
countOnly(array, itemsToCount)
: takes in an array and an object, and returns an object containing only the count of each array value that held a truthy value in the input object. -
findKey(object, callback)
: returns the key (as a string) of the first property that satisfies the provided callback function. -
findKeyByValue(object, value)
: returns the key (as a string) of the first property that's value matches the provided input value. -
flatten(array)
: returns an array virtually-identical to the input however with no nested arrays and all formerly nested values present. -
head(array)
: returns the first value in an array. -
middle(array)
: returns the middle value/values of an array. -
tail(array)
: returns a new array without the initial value. -
map(array, callback)
: returns a new array in which the contents have been altered by a callback function. -
letterPositions(string)
: returns an object that lists the positions that each letter resides in a string. -
takeUntil(array, callback)
: returns a new array that lists all items of the original array up until the provided callback function is no longer satisfied. -
without(array, itemsToRemove)
: returns a new array without any value provided in the itemsToRemove argument.
