This project was created and published by me as part of my learnings at Lighthouse Labs.
Usage
Install it:
npm install @turnipboy/lotide
Require it:
const _ = require('@turnipboy/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]

The following functions are currently implemented:
-
assertArraysEqual(array1, array2)
: assert whether two arrays are equal. -
assertEqual(actual, expected)
: assert whether two primitive variables are equal. -
assertObjectsEqual(object1, object2)
: assert whether two objects are equal. -
countLetters(string)
: count and return the number of letters in a string. -
countOnly(allItems, itemsToCount)
: takes an array of elements and an object of elements with value true if needed to be counted in the array, returns object with elements counted and count as value. -
eqArrays(array1, array2)
: check to see if two arrays are equal in length and values, returns boolean. -
eqObjects(object1, object2)
: check to see if two objects are equal in length and values, returns boolean. -
findKey(object, callback)
: takes in an object and a callback function that gives the value to be found, returns the first property with the value, otherwise return undefined. -
findKeyByValue(object, value)
: takes an object and the value to be found, returns the first property with the value, otherwise return undefined. -
letterPositions(string)
: takes a string and returns an object with properties being all the letter in the string with an array of positions they appear at as the value. -
map(array, callback)
: takes an array and a callback function, the operation in the callback will be done to the array and stored in a new array, returns a new modified array. -
takeUntil(array, callback)
: takes an array and a callback function, add elements of the array into a new array as long as the condition in the callback is true, returns a new modified array. -
without(array1, array2)
: takes two arrays and return an array that has all elemnts in the first array minus elements in the second array. -
head(array)
: returns the head of an array. -
tail(array)
: returns the tail of an array. -
middle(array)
: returns the middle of an array.
