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 @markmdoza/lotide
Require it:
const _ = require('@markmdoza/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
assertArraysEqual(arr1, arr2)
: Checks and logs a message if arr1 equals arr2.assertEqual(actual, expected)
: Checks and logs a message if actual is equivalent to expected. Should be stacked onto other functions that include 'assert'.assertObjectsEqual(actual, expected)
: Checks and logs a message if actual is equivalent to expected.countLetters(string)
: Returns an object with each letter in the string provided, and how many times each letter is within the string.countOnly(allItems, itemsToCount)
: Returns an object of each name in itemsToCount as well as the amount of the times it appears in allItems.eqArrays(array1, array2)
: Checks and returns a boolean if array1 is equal to array2.eqObjects(object1, object2)
: Checks and returns a boolean if object1 is equal to object2findKey(object, callback)
: Loops through keys in an object and returns a truthy value set by the callback function. If no key is found, then undefined will be returned instead.findKeyByValue(obj, value)
: Loops through object keys and returns the value that was passed through.flatten(array)
: If a nested array is passed through, it will return a new array without any nests.head(array)
: Returns the first element in an array.letterPositions(string)
: Returns all indices in a string, where each character is found.map(array, callback)
: Returns a new array based on the condition of the callback function.middle(array)
: Returns the middle most value(s) in an array.tail(arr)
: Returns all elements in an array after index[0].takeUntil(array, callback)
: The function will return a slice of the array with elements taken from the beginning. It will keep going until the callback condition is met.without(source, itemsToRemove)
: Returns elements in source, excluding elements in itemsToRemove.
