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

npm install @sandypockets/lotide
Require it:
const _ = require('@sandypockets/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(...)
: Checks if the contents of two arrays are equal, and return an assertion message. -
assertEqual(...)
: Returns assertion message. -
assertObjectsEqual(...)
: Checks if two objects contain equal contents, and returns an assertion message. -
countLetters(...)
: Checks the number of occurrences of each letter in a string. -
countOnly(...)
: Checks the number of occurrences a string (in this case a name) occurs in an array. -
eqArrays(...)
: Checks if two arrays are equal. -
eqObjects(...)
: Checks if two objects are equal. -
findKey(...)
: Scans the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined. -
findKeyByValue(...)
: // Scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined. -
flatten(...)
: Takes an array of nested arrays, and returns a single array, without any nesting. -
head(...)
: Returns the first element of an array. -
letterPositions(...)
: Returns the position of a particular letter/character. -
map(...)
: Vanilla JS map function. Creates a new array populated with the results of calling the function on every element in the array it is called on. -
middle(...)
: Returns the middle element of an array. Arrays with odd numbers return one element, while arrays with even numbers return two elements. -
reverse(...)
: Reverses a word. -
tail(...)
: Removes the head (first element) of an array, and returns the remainder of the array as is. -
takeUntil(...)
: The function will return a slice of the array with elements taken from the start of the array. It runs until the callback returns a truthy value. -
without(...)
: Removes an element (supplied by you) to remove from the array, then returns the entire array without that specific element.
