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 @aceflanker/lotide
Require it:
const _ = require('@aceflanker/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
eqArrays(array1, array2): Returns true for two identical arrays, false otherwise.eqObjects(object1, object2): Returns true for two identical objects, false otherwise.flatten(array1): Returns a new array with elements of children arrays (one level deep) expanded into the outer array in addition to all other elements of non-objects in the outer array.without(source, unwantedElements): Returns a new array from an argument array with elements removed per the other argument array provided.head(array1): Returns a new array with the element at index 0 of the argument array.tail(array1): Returns a new array with all other elements than the one at index 0 in the argument array.middle(array1): Returns a new array with the element or elements at the halway index or indices in an array of an odd or of an even number of elements, respectively.countOnly(array1, elementsToCount): Returns an object with keys representing the elements needed to account for and values representing their number of occurrences in an array.countLetters(string1)): Returns an object with keys representing the characters and values representing their number of occurrences in a string.letterPositions(string1): Returns an object with keys representing the characters and values, as arrays of numbers representing their indices in a string.findKeyByValue(object1, wantedProperty): Return true a key in an object, if the key contains the value specified in the corresponding argument, false otherwise.findKey(object1, callBackFunction): Returns the first key whose value matches that specified in the callback function.map(array1, callBackFunction): Returns a new array with results given by a function called back on the arugment array.takeUntil(array1, callBackFunction): Returns a portion of an array as new, starting from the first element to a latter one as specified by the callback function.
