A mini clone of the Lodash library.

**BEWARE: This library was published for learning purposes. It is not intended for use in production code

This projecgt was created and published by me as part of my lernings at Lighthouse Labs.

Install it:

npm install @christian_bowyer/lotide

Require it:

const_= require('@christian_bowyer/lotide');

Call it:

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

The following functions are currently implemented:

assertArraysEqual(actual, expected): Function that takes 2 arrays, actual and expected and asserts whether they equal or not.
assertEqual(actual, expected): Function that takes 2 parameters, actual and expected &asserts whether they are = or not.
assertObjectsEqual(actual, expected): Function that takes 2 objects, actual and expected and asserts whether they are = or not
countLetters(string): Function that takes string and returns object with the letters as keys and the amount of times that letter appears in the string as the value
countOnly(allItems, itemsToCount): Function that takes an array and an object which specifies which items to count in the array by assigning t or f as value to the key. Returns an object with the items that have been counted as keys and the amount of times they appear as the corresponding value.

-eqArrays(actual, expected): Function that takes 2 arrays and returns true if they are equal and false if they are not.

eqObjects(actual, expected): Function that takes 2objects and returns true if they are = and false if they are not.
findKey(object, callback): Function that takes an object and a callback where the callback takes in the object keys as parameters. When the callback function returns t, the function will return the key that yieled the true result.
findKeysByValue(object, value): Function that takes an object and value, it will iterate through the object's keys and when the key value = the value passed in, it will return the key that contains that value.
flatten(nestedarray): Function that takes a single layer nested array and returns a single array with all the same items but without the nest

-head(array): Function that takes an array and returns the item at index 0.

-tail(array): Function that takes in an array and returns all items after index 0.

middle(array): Function that takes in an array and returns the item at the mid index or mid indexes.
letterPositions(string): Function that takes in a string and returns an object with the letters as keys and and array of index numbers at which that letter appears in the string as values.
map(array, callback): Function that takes in an array and callback function and passes each item of that array through the callback function and returns a new array with the results.
takeUntil(array, callback): Function that takes in an array and callback function and returns everything in the array up until the item that when passed into the callback function returns true.
without(array1, array2): Function that takes in two arrays and removes items from the first that also exist in the second.git
