Usage

Install it:

npm install @adrianetodesign/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): Returns the head of a given array.
• tail(array): Returns the tail of a given array.
• middle(array): Returns the middle value(s) of given arrays with length longer than 2. Otherwise returns an empty string.
• eqArrays(array1, array2): Returns true if both given arrays are strictly equal.
• eqObjects(object1, object2): Returns true both given objects are strictly equal.
• assertEqual(variable1, variable2): Logs an assertion message if both primitive variables are strictly equal.
• assertArraysEqual(array1, array2): Logs an assertion message if both arrays are deeply equal.
• assertObjectsEqual(object1, object2): Logs an assertion message if both objects are deeply equal.
• countLetters(string): Returns an object that has a count of how many times each letter appears within a string. Does not count spaces. Each letter is represented as a key of the object, with the count as it's value.
• countOnly(array, object): Counts only items that appear in the given array based on a given object. If any values of keys in the object are false, those items will not be counted. Object must follow format of {itemName: true, itemName2: false}.
• findKey(object, callback): Returns the first key in a given object that fulfills the conditions of the callback function.
• letterPositions(string): Returns an object with the index for each letter. Each letter is represented as a key of the object, with the indices stored in an array as it's value.
• map(array, callback): Returns an array with the given callback function applied to each item of the array.
• takeUntil(array, callback): Returns an array with the given array sliced until the given callback function returns a truthy value.
• without(array1, array2): Returns the first given array with all values in the second given array removed.
