Lotide
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 Lotide:
npm install @ballsy/lotide
Require Lotide:
const _ = require('@ballsy/lotide');
Call Lotide:
const results = _.tail([1, 2, 3]) // => [2, 3]`
Documentation
The following functions are currently implemented:
-
assertArraysEqual(actual, expected)
: Strictly compares input array to the expected output array. Logs the pass or fail to the console. -
assertEqual(actual, expected)
: Stricly compares input primitive values to the expected output. Logs the pass or fail to the console. -
assertObjectsEqual(actual, expected)
: Stricly compares input primitive values to the expected output. Logs the pass or fail to the console. -
eqArrays(Arr1, Arr2)
: Strictly compares two input arrays. Returns true or false. -
eqObjects(object1, object2)
: Strictly compares two input objects. Returns true or false. -
countLetters(str)
: Takes and input string and returns the number of letters & characters, less the whitespace. -
countOnly(allItems, itemsToCount)
: Takes an input array and an object populated with the elements to be counted (if truthy) or not (if falsey).Returns an object with the results. -
findKey(object, callback)
: Takes an object and function to execute it. Searches for a key in the object that matches the conditions given and returns the first key name found that matches. -
findKeyByValue(obj, value)
: Takes an object and a value to search for. Searches for a key in the object that matches the specified value. -
flatten(source)
: Takes a source array with a nested array and returns a single "level" array. (Not recursive. Only a single level of nesting can be flattened at a time.) -
head(Arr)
: Takes an array and returns the element at the first index. -
letterPositions(str)
: Takes a string and returns an object with the index of each occurrence of each character in the string. Occurrence of whitespace is not returned. -
map(array, callback)
: Takes an array and a function to be executed on the array. Returns a new array with the results. -
middle(array)
: Takes an array and returns the value at the middle index position. Returns two values if the length of the array is even. -
tail(Arr)
: Takes an array and returns it without the element at the first index of the input array. -
takeUntil(array, callback)
: Takes an array and a function to be executed on it. Loops over the array and returns it as is until it hits the break condition of the callback. -
without(source, itemsToRemove)
: Takes a source array and array of unwanted items. Returns a new array with only those elements from the source array which are NOT present in the itemsToRemove array. Stricly compares the values between both arrays.
