@mikenguyentt/lotide v1.0.1

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 @mikenguyentt/lotide

Require it:

const _ = require('@mikenguyentt/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• head(array): return first element of the input array
• tail(array): return input array except the first element
• middle(array): return middle element/s of input array, one element if input array length is odd, and two elements if input array length is even
• assertArraysEqual(array1, array2): to assert if an actual array is equal to an expected array
• assertObjectsEqual(object1, object2): to assert if an actual object is equal to an expected object
• assertEqual(value1, value2): to assert if an actual value is equal to an expected value
• countLetters(string): count the occurences of every letter in the given sentence
• countOnly(object1, object2): take in a collection of items in object1 and return counts for a specific subset of those items
• eqArrays(array1, array2): compare two arrays, return true if both are equal and false otherwise
• eqObjects(object1, object2): compare two objects, return true if both are equal and false otherwise
• findKey(object, callback): return the key of the object depending on the callback function condition
• findKeyByValue(object, value): return the key name of a given value if found in the object
• flatten(nestedArray): take in a multilevel nested array, remove all the nest and return a flat array with all elements
• letterPositions(string): return an object whose every value is an array of indices when the key letter appears
• map(array, callback): return a new array containing elements as the result of callback function manipulating input array.
• takeUntil(array, callback): return a new array only with head elements until the callback function condition is matched
• without(array1, array2): filter out all the element of array2 from the array1 };
