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 @trentpf/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the first value of an array, undefined if an empty array
• tail(array): returns all values (array) except the first of an array, undefined if array length is less than or equal to 1
• middle(array): returns the middle values (array) of an array, returns 1 value if odd length, 2 if even length, returns undefined if array length is less than or equal to 2
• map(array, callback): returns a new array created by calling a callback function argument on the array argument
• letterPositions(sentence): returns an object containing properties of array values that hold the index of each non-space character that occurs in the string
• flatten(array): returns array argument "flattened", any values of outer array that are arrays themselves are turned into sequential values in the outer array
• findKeyByValue(objectToSearch, value): returns the string of the property key where the value argument occurs
• findKey(object, callback): returns property key of object argument based on callback function argument
• countOnly(allItems, itemsToCount): returns an object of counted values in an argument array allItems based on object argument listing which items to count
• countLetters(sentence): returns an object containing how many times each letter occurs in argument sentence
