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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): assert whether two arrays are equal.
• assertEqual(actual, expected): assert whether two primitive variables are equal.
• assertObjectsEqual(object1, object2): assert whether two objects are equal.
• countLetters(string): count and return the number of letters in a string.
• countOnly(allItems, itemsToCount): takes an array of elements and an object of elements with value true if needed to be counted in the array, returns object with elements counted and count as value.
• eqArrays(array1, array2): check to see if two arrays are equal in length and values, returns boolean.
• eqObjects(object1, object2): check to see if two objects are equal in length and values, returns boolean.
• findKey(object, callback): takes in an object and a callback function that gives the value to be found, returns the first property with the value, otherwise return undefined.
• findKeyByValue(object, value): takes an object and the value to be found, returns the first property with the value, otherwise return undefined.
• letterPositions(string): takes a string and returns an object with properties being all the letter in the string with an array of positions they appear at as the value.
• map(array, callback): takes an array and a callback function, the operation in the callback will be done to the array and stored in a new array, returns a new modified array.
• takeUntil(array, callback): takes an array and a callback function, add elements of the array into a new array as long as the condition in the callback is true, returns a new modified array.
• without(array1, array2): takes two arrays and return an array that has all elemnts in the first array minus elements in the second array.
• head(array): returns the head of an array.
• tail(array): returns the tail of an array.
• middle(array): returns the middle of an array.
