@saranyasagi/lotide v1.0.0

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 @saranyasagi/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head: displays first item of the array
• tail: displays trailing items of firts item in array.
• middle: takes array, checks if even or odd, or single element and double elements, and outputs the middle most number/numbers accordingly.
• assertEqual: Own version of assert.equal that checks if expected is strictly equal to actual
• eqArrays: Check if 2 arrays are equal in length and values.
• assertArraysEqual: Assertion test version to check if expected array matched actual value in length and values.
• without: takes in 2 parameters, a given array and items to remove in a separate parameter, based on the parameter, outputs array with the items to remove items removed.
• takeUntil: return a slice of array with elements taken from the beginning, has 2 parameters an array and a callback
• map: has 2 parameters, an array and a callback, returns new array based on callback results or conditions.
• letterPositions: takes in a single sentence/string parameter, returns all the indeces where the letters occur in arrays without counting spaces.
• findKey: 2 parameters a callback and object, scan the object and return first key that callback says is truthy.
• eqObjects: test to see that 2 objects are equal, they should have same number of keys and value of each object key should also be checked to be equal. 2 parameters are object 1 and object 2.
• countOnly: takes in 2 parameters allItems and itemstoCount, based on itemstoCount parameter matched outputs resulting count only for those matched.
• countLetters: take in a sentence and return count of each letter not including spaces and output data as an object with key values.
• assertObjectsEqual: won't be doing assertion test with this, just for manual checks, there will be side effects.
