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 @tapansiwach/lotide
Require it:
const _ = require('@tapansiwach/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(array1, array2): Uses eqArrays function in this library to check for equality and then asserts if the two arrays are equal. -
assertEqual(actual, expected): Asserts if two input values (of primitive types) are equal. -
assertObjectsEqual(object1, object2): Uses eqObjects function in this library to check for equality and then asserts if the two objects are equal. -
countLetters(sentence): Counts the frequency of occurance of different letters in a sentence -
countOnly(array, object): Counts the frequency of occurance of items in an array if they are described as to be counted via a given object. -
eqArrays(array1, array2): Checks if two arrays are equal. -
eqObjects(object1, object2): Checks if two objects are equal. -
findKey(object, callback): Finds a key in an object which satisfies the condition evaluated through a given callback. -
findKeyByValue(object, value): Finds an object's key corrosponding to a provided value. -
flatten(deepArray): Flattens a deep / nested array. -
head(array): Returns the first item of an array. -
letterPositions(sentence): Returns an object which contains the position(s) of diferrent letters in a sentence. -
map(array, callback): Maps the items of an array as per a provided callback. -
middle(array): Returns the middle (if length of an input array is odd) or middle two items (if length of an input array is even) of an array. -
tail(array): Returns the last two indicesc of an array. -
takeUntil(array, callback): Returns an array containing items of a provided array until an item in the provided array meets a condition (defined by a callback). -
without(array1, array2): Returns an array which contains items in a source array (array1) without the items contained in another array (array2).
