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 @sfraser/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): compares two arrays and asserts if they are equal.

• assertEqual(actual, expected): compares primitive data types and asserts if they are equal.

• assertObjectEqual(actual, expected): compares two objects and asserts if they are equal.

• countLetters(letters): takes the letter count of a string and returns the value.

• countOnly(allItems, itemToCount): allItems is an array that needs to be looked through an itemsToCount specifies what to count.

• eqArrays(array1, array2): takes two arrays and returns true if they are equal and false if they are not.

• eqObjects(object1, object2): compares two objects and returns true if they are equal and false if they are not.

• findKey(object, callback): takes an object and callback function to be applied to a specific key.

• findKeyByValue(object, value): takes an object and value and returns a key with the specified value.

• head(array): takes an array and returns the first value in that array.

• letterPositions(string): takes a string and returns an object where the keys are the letter and the value is an array of the letters location in the original string.

• map(array, callback): takes an array and callback and allows the callback to be executed on every value in that array and returns a new array.

• middle(array): takes an array and returns the middle value or values (if it is an even number in length array) of the array

• tail(array)): takes an array and returns the array without the first value.

• takeUntil(array, callback): takes an array and callback and returns the array up until the point callback is acheived.

• without(array1, array2): takes two arrays and returns a new array that has all the elements in array1 not found in array2.
