#Lotide
A mini clone of the Lodash library.
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.
Install it:
npm install @tarinkazi/lotide
Require it:
const _ = require('@tarinkazi/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
*assertEqual(val1, val2) : Checks two non-array values and returns true if they are identical, or false if they are not. *assertObjectsEqual(obj1, obj2) : Compares two objects to see if they are identical. Supports 1 level of array nesting within the object. Supports unlimited nested objects. *countLetters(str) : Returns an object with a list and number of occurences fo characters in the supplied str. *countOnly(arr, elem): Returns a count of how many times the element appears in the array. *eqArrays(arr1, arr2) : Compares two arrays, returns true if they are identical. Supports unlimited nesting of arrays. *findKey(obj, cb()) : Given an object and callback function, finds the first key for which that value occurs.
*findKeyByValue(obj, valueStr) : Given an object and value, finds the first key for which that value occurs. No callback function necessary. *head(arr) : Returns the first item in an array. letterPositions(str) : Given a string, returns an object with the position(s) of each letter in the string. *map(arr, cb) : Given an array, returns a new array which meets the conditions of the supplied callback function. *middle(arr) : Returns the middle element(s) of an array. If array size < 2, returns an empty array. *tail(arr) : Removes first element and returns the rest of the array. *takeUntil(arr, cb): Given an array, returns a new array with all elements (from left to right) until the callback function criteria is met. *without(arr1, arr2): Returns a new array where values of array 2 are not present in array 1.
