@clsnazel/lotide v1.0.0

Lotide

A mini clone of the Lodash library. As part of the first week of webdev bootcamp at Lighthouse Labs.

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 @clsnazel/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(inputString:String): returns an object, with each non-space character as keys, and count of occurances in the string as the value.
• countOnly(arr:Array, countObj:Object): returns an object, counting the number of times a key appears in arr when key:true in the countObj
• eqArrays(actualArr:Array, expectedArr:Array): completes a deep comparison of two arrays, accepts nested arrays and objects.
• eqObjects(obj1:Object, obj2:Object): completes a deep comparison of two object, accepts nested arrays and objects.
• findKey(obj:Object, callback:Function): given a callback function that returns truthy, return the first key that triggers callback to return true.
• findKeyByValue(obj:Object, val): given a value in val, return the first key that has a matching value to val.
• flatten(arr:Array): given a multi-dimensional array, return a flattened array without any nesting.
• head(arr:Array): given an array, returns the first value in the array.
• letterPositions(sentence:String): given a string, return an object with each non-space character in the sentence as a key. Each key has an array of index values of where it occurs in the string.
• map(arr:Array, callback:Function): given an array, complete the callback with each array item as a parameter, and returns each callback result as a new array.
• middle(arr:Array): given an array, returns the one or two middle values of that array as a new array.
• tail(arr:Array): returns all items in the array excluding the first item, as a new array.
• takeUntil(arr:Array, callback:Function): given a callback, will return the array up until an array element that causes the callback to return true.
• without(initArr:Array, removeArr:Array): given two arrays, matching values between removeArr and initArr will be removed from initArr and returned as a new array.
