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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(expected, actual): Prints the result of a strict comparison between two values of primitive data types.
• head(array): Returns the first element of an array.
• tail(array): Returns an array consisting of all but the first element of the array.
• eqArrays(array1, array2): Performs a deep comparison between two arrays.
• assertArraysEqual(array1, array2): Prints the result of a deep comparison between two arrays.
• without(source, itemsToRemove): Returns an array consisting of all elements in the source array except for those included in the itemsToRemove array.
• flatten(array): Convert a nested array into an unnested array.
• middle(array): Returns the middle element(s) of an array.
• countOnly(allItems, itemsToCount): Counts the occurence of each element in the allItems array that is a key in the itemsToCount object and has a value of true.
• countLetters(string): Counts the occurrence of each character in a string.
• letterPositions(string): Returns the position(s) of each character in a string.
• findKeyByValue(object, value): Returns the first key of an object that has a value equal to value.
• eqObjects(object1, object2): Performs deep comparsion between two objects.
• assertObjectsEqual(object1, object2): Prints the result of a deep comparison between two objects.
• map(array, callback): Returns an array with the callback function applied to each element of an array.
• takeUntil(array, callback): Returns a slice of an array with elements taken from the beginning, until callback function returns a truthy value.
• findKey(object, callback): Returns the first key of an object for which the callback returns a truthy value.
