npm install @glowiep/lotide
Require it:
const _ = require('@glowiep/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]

assertEqual(actual, expected): Takes in 2 values and returns true if they are equal and false otherwise. -
assertObjectsEqual(actual, expected): Takes in 2 objects and asserts whether two arrays are equal. -
countLetters(sentence): Takes in a sentence (string) and returns a count of each of the letters in the sentence. -
countOnly(allItems, itemsToCount): Takes in a collection of items and returns a specific subset of those items. -
eqArrays(array1, array2): Takes in 2 arrays and returns true if the arrays are equal and false otherwise. -
eqObjects(object1, object2): Takes in 2 objects and return true if they are equal and false otherwise. -
findKey(object, callback): Takes in an object and callback and returns the first key that meets the criteria specified in callback. -
findKeyByValue: Takes in an object and a value and returns the first key that corresponds to that value. -
flatten(array): Takes in an array that contains elements including nested array of elements, and returns a flattened version of the array. -
head(array): Returns the first element in the array. -
letterPositions(sentence): Returns all indices of letter positions in the sentence (string). -
map(array, callback): Returns a new array based on the results of the callback on each item in the array. -
middle(array): Returns middle most element of the array. -
tail(array): Returns everything except the first element of the array. -
