npm install smalboeuf/lotide

Require it:

const _ = require('smalboeuf/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the first element of the passed array.
• tail(array): returns the passed array minus the first element.
• middle(array): returns the middle value(s) of the passed array.
• assertArraysEqual(array1, array2): asserts the equality of the two passed arrays.
• assertEqual(element1, element2): compares the two passed elements and asserts their equality.
• assertObjectEqual(object1, object2): compares the two passed objects and returns and asserts their equality.
• countLetters(sentence): counts the letters in the passed sentence.
• countOnly(allItems, itemsToCount): counts the designated item and returns the count as an object with the key being the item, and the value being its count.
• eqArrays(array1, array2): compares the two passed arrays and returns a true or false value depending on if they are equal or not.
• eqObjects(object1, object2): compares the two passed objects and returns a true or false value depending on if they are equal or not.
• findKey(object, callback): scans the object and return the first key for which the callback returns a truthy value.
• findKeyByValue(object, key): scans the object and return the first key which contains the given value.
• flatten(array): Takes an array of arrays and return a "flattened" version of the array.
• letterPositions(sentence): Takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• map(array, callback): takes in an array, applies modifications specified in the callback, then returns elements in the array.
• takeUntil(array, callback): will keep collecting items from a provided array until the callback provided returns a truthy value.
• without(array, itemsToRemove): will return a subset of a given array, removing unwanted elements.
