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 @brettg17/lotide
Require it:
const _ = require('@brettg17/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(actual, expected): tests whether two arrays are equal or not -
assertEqual(actual, expected): tests if a functions actual return is equal to the expected -
assertObjectEqual(actual, expected): test whether two objects are equal -
countLetters(chars): counts letters in a string -
countOnly(allItems, itemsToCount): checks how many times and item is in an array. returns undefined if not -
eqArrays(arrayOne, arrayTwo): tests to see if two arrays are equal -
eqObjects(object1, object2): tests to see if keys and values in an object are equal -
findKey(obj, callback): uses callback and returns true if truthy value is meant. if not return undefined -
findKeyByValue(genre, show): finds key by value. if value/key is not in the object return undefined -
countOnly(allItems, itemsToCount): checks how many times and item is in an array. returns undefined if not -
flatten(arr): takes an array with elements that include nested arrays. removes nested arrays creating a "flattened" array -
head(arr): returns first element of an array -
letterPositions(sentence): returns what position letters in a string are in. -
map(array, callback): map function returns an array based on the reults of the callback function -
middle(array): returns middle element of an array. middle two elements of even. empty array if two elements or less -
tail(arr): creates new array exluding first element in original array -
takeUntil(array, callback): return elements in an array up to the point truthy condition is met. -
without(source, itemsToRemove): whatever elements that are in first array but not in second will get pushed into new array.
