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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): Evaluate array1 and array2 then log the results
• assertEqual(value1, value2): Evaluate value1 and value2 then log the results
• assertObjectsEqual(obj1, obj2): Evaluate obj1 and obj2 then log the results
• countLetters(string): Return an object containing character counts for each character in string
• countOnly(allItems, itemsToCount): Return an object containing instance counts for each element in allItems
  • allItems: an array of strings (e.g., ['1', '1', '2'])
  • itemsToCount: an object of elements with a boolean value indicating whether or not it should be counted (e.g., {'1': true, '2': false})
• eqArrays(array1, array2): Evaluate array1 === array2
• eqObjects(obj1, obj2): Evaluate obj1 === obj2
• findKey(object, callback): Return the first key in object for which the callback function returns true
• findKeyByValue(object, value): Return the first key in object with the given value
• flatten(array): Return a nested array as a single-level array
• head(array): Return the first element of array
• letterPositions(sentence): Return an object containing the indices for which each character in sentence is found
• map(array, callback): Return a new array with the results of calling the callback on each element in array
• middle(array): Return the middle element(s) of array
• tail(array): Return an array containing every element after the head of array
• takeUntil(array, callback): Return all elements of array until an element for which the callback function is applied to returns true
• without(source, itemsToRemove): Return a new array with elements in source (array) that are not in itemsToRemove (array)
