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 @tony_walker101/lotide
Require it:
const _ = require('@tony_walker101/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]

-
assertArraysEqual(actualArray, expectedArray): Takes in 2 arrays and returns "Passed" if they're equal and "Failed" if they're not. -
assertEqual(actualFoo, expectedFoo): Takes in 2 values and returns "Passed" if they're equal and "Failed" if they're not. -
assertObjectsEqual(actualObject, expectedObject): Takes in 2 objects and returns "Passed" if they're equal and "Failed" if they're not. -
counterLetters(string): Takes in a sentence and returns a count of each letter in the sentence. -
countOnly(allItems, itemsToCount): Takes in an array of items and returns a subset of those items. -
eqArrays(actualArray, expectedArray): Takes in 2 arrays and returns "True" if they're equal and "False" if they're not. -
eqObjects(actualObject, expectedObject): Takes in 2 objects and returns "True" if they're equal and "False" if they're not. -
findKey(object, fn): Takes in an object and a function and returns the first key that matches the criteria of the function. -
findKeyByValue(object, foo): Takes in an object and a value and returns the first key equal to that value. -
flatten(array): Takes in an array that contains nested arrays and returns a version of the array with no nests. -
head(array): Takes in an array and returns the first element of the array. -
letterPositions(string): Takes in a string and returns indices of letter positions in the string. -
map(array, fn): Takes in an array and a function and returns a new array that matches the criteria of the function. -
middle(array): Takes in an array and returns the middle most element(s) of the array. -
tail(array): Takes in an array and returns everything except the first element of the array. -
takeUntil(array, fn): Takes in an array and a function and returns a slice of the array based off the criteria of the function. -
without(array, itemsToRemoveArray): Takes in 2 arrays and returns only the items not common between the two arrays.
