npm install @checkeve/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): takes in two arrays and logs a message to the console stating whether or not the two arrays are equal
• assertEqual(actual, expected): logs a message to the console stating whether or not the two arrays passed to it are equal
• assertObjectsEqual(object1, object2): takes in two objects and logs a message to the console showing whether or not they are a perfect match.
• countLetters(sentence): takes in a sentence (as a string) and then returns a count of each of the letters in that sentence
• countOnly(allItems, itemsToCount): takes in a collection of items and returns counts for a specific subset of those items
• eqArrays(array1, array2): takes in two arrays and returns true or false based on whether they are equal to each other
• eqObjects(object1, object2): takes in two objects and returns true or false, based on a perfect match
• findKey(object, callback): takes in an object and a callback and scans the object, returning the first key for which the callback returns a truthy value
• findKeyByValue(obj, value): takes in an object and a value, scans the object and return the first key which contains the given value
• flatten(nestedArray): takes in an array containing elements including nested arrays of elements, and returns a "flattened" version of the array
• head(array): returns the first item in the array passed to it
• letterPositions(sentence): returns all the indices (zero-based positions) in the string where each character is found
• map(array, callback): returns a new array based on the results passing each element in the array to the callback function
• middle(array): takes in an array and returns the middle-most element(s) of the given array
• tail(array): returns an array of every item in the array passed to it except the first
• takeUntil(array, callback): returns a slice of the array passed to it with elements taken from the beginning up until the callback returns a truthy value
• without(source, itemsToRemove): returns a subset of the source array that is passed to it, removing elements indicated in the itemSToRemove array
