Usage

Install it:

npm install @adamhirzalla/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(actual, expected): logs assertion message - Pass/Fail (operator: ===)
• eqArrays(firstArray, secondArray): returns true if both arrays are equal, otherwise false (operator: ===)
• assertArraysEqual(firstArray, secondArray): logs assertion message - Pass/Fail (operator: ===)
• eqObjects(firstObject, secondObject): returns true if both objects are equal, otherwise false (operator: ===)
• assertObjectsEqual(firstObject, secondObject): logs assertion message - Pass/Fail (operator: ===)
• head(array): returns the head element of a given array
• tail(array): returns the tail array of a given array
• middle(array): returns an array of the middle element for a given array
  • If array length is less than or equal 2: returns an empty array
  • If array length is odd and greater than 2: returns an array with the middle element
  • If array length is even and greater than 2: returns an array with both middle elements
• flatten(array): flattens a given array into a single array
• map(array, callback): calls a given callback function on every element of a given array
• countLetters(string): returns an object with each character from a given string as the key, and its number of occurances as the key-value
• countOnly(allItems, itemsToCount): given an object itemsToCount with keys of what to count and a value of true/false, returns an object with number of occurances of each key from a given array of allItems
• findKey(object, callback): returns the key-name of the first truthy return of the callback function on a given object
• findKeyByValue(object, value): returns the key-name of the first key-value matching the given value
• takeUntil(array, callback): returns an array with all elements of a given array until it reaches a truthy return value from the given callback function
• without(allItems, elementsToRemove): removes all instances of elements from a given array elementsToRemove from a main given array allItems
• lettPositions(string): returns an object with keys of all characters and their indices as key-values from a given string
