@riazckhan/lotide v1.0.2

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 @riazckhan/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(...): will generate an assertion passed 😇 / failed 🤬 statement.

• assertArraysEqual(...): will generate an assertion passed / failed statement based the comparison of two arrays given their lengths and values.

• assertObjectsEqual(...): utilizing the util library, this function will assert if two objects are equal based on their properties.

• countLetters(...): will count the number of times each letter/characters is present in a string and return the result as an object.

• countOnly(...): provide the function with an 'allItems' and 'itemsToCount' argument and receive a list of solely composed of the desired items, i.e., 'itemsToCount'.

• eqArrays(...): will return true if the two array arguments provided are equal in lengths and values; otherwise false.

• eqObjects(...): will return true if the two object arguments provided are equal in lengths and key/value pair properties; otherwise false.

• findKey(...): given an object and callback, a desired value can be pulled from the object by providing the callback function with the desired argument.

• findKeyByValue(...): given an object and a value, the function will return the key associated with the provided value, i.e., the key/value pair.

• flatten(...): given a nested array of numbers, this function will 'flatten' all arrays and return one array.

• head(...): will return the first element of an array.

• middle(...): will return the middle index of an array. When given an array with an even number of elements the function will return the 2 'middle' index values.

• tail(...): will return the last element of an array.

• letterPositions(...): will return the index position of a character in the provided string.

• takeUntil(...): will reduce a string and return the reduced string. The point of reduction is determined by the callback function.

• without(...): will remove an element from an array and return the mutated array.
