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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Tests whether two different arrays are equal to one another
• assertEqual(actual, expected): Compares two values with one another and returns true or false
• assertObjectsEqual(obj1, obj2): Compares two objects with one another
• countLetters(word): Takes in a word, returns an object that allocates number of particular letter into a key: value pair
• countOnly(allItems, itemsToCount): Takes in a collection of items and return counts for a specific subset of those items
• eqArrays(arr1, arr2): Compares two arrays for a perfect match
• eqObjects(obj1, obj2): Compares two objects for a perfect match
• findKey(obj, fn): Takes in an object and a callback, returns the first key for which the callback returns a truthy value.
• `findKeyByValue(obj,objVal): Takes in an object and a value, scans the object, return the first key which contains the given value
• head(first): Takes first element from an array
• letterPosition(sentence): Takes in one argument, return indices (zero-based positions) in the string where each character is found
• map(array,callback): The map function will return a new array based on the results of the callback function
• middle(midArray): Takes in a single argument, returns the middle element of an array.
• tails(arr): Takes every element but the first, slices into new array.
• takeUntil(array, callback): Takes in two arguments, returns slice of the array with elements taken from the beginning. Stops when callback returns a truthy value
• without(source, itemsToRemove): Compares two arrays, takes out elements present in itemsToRemove array.
