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 @chanoonna/lotide
Require it:
const _ = require('@chanoonna/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual([ array 1 ], [ array 2 ]): Assertion test for 2 arrays. (Does not return anything) -
assertEqual(value 1, value 2): Assertion test for 2 primitive types. (Does not return anything) -
assertObjectsEqual({ object 1 }, { object 2 }: Assertiontest for 2 objects (Does not return anything) -
countLeters("string"): Returns an object with characters present in the given string and their occurrence. (Returns empty object when given an empty string and throw an error when given argument is not a string.) -
countOnly([ array ], { object }): Counts array elements with a given objects. Returns an object with occurrence of items. -
eqArrays([ array 1 ], [ array 2 ]): Returns true if both arrays have same elements, if not returns false. -
eqObjects.js({ object 1 }, { object 2 }): Returns true if both objects have same properties and their values, if not returns false. -
findKey({ object }, callback): Returns value if it exists or an empty array if it doesn't. -
findKeyByValue( value ): Returns an array of keys found if they exists or an mepty array if it doesn't. -
flatten([ array ]): Returns a flattened array. (Flattens nested arrays as well) -
head([ array ]): Returns the first element of the given array. Returns an empty array if the length of array is less than or equal to 1. -
isObject({ object }): Returns true if given argument is an object type, false if not. -
letterPositions("string"): Returns an object with property names as characters and their values are an array of index of the character. -
map([ array ], callback): Returns a new array with elements processed by callback function. -
middle([ array ]): Returns a middle element in an array. (or 2 for even length array) Returns an empty array if the array is shorter or equal to 2. -
tail( [ array ]): Returns an array excluding the first element of the given array. Returns an empty array if given an array shorter or equal to 1. -
takeUntil([ array ], callback): Returns an array with elements up until the callback function defines. -
without([ array 1 ], [ array 2]): Returns and array excluding the elements present in array 2.
