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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): Check if two arrays are equal, show the result on terminal.
• assertEqual(actual, expected): Check if two primitive type elements are equal, show the result on terminal.
• assertObjectsEqual(object1, object2): Check if two objects are equal, show the result on terminal.
• countOnly(allItems, itemsToCOunt): Count the number of an element in allItems based on itemsToCount object.
• eqArrays(array1, array2): Check if two arrays are equal, return boolean values.
• eqObjects(object1, object2): Check if two objects are equal, return boolean values.
• findKey(object, callback): Return the first key that callback(value) returns true, return undefined if no elements match callback requirements.
• findKeyByValue(object, value): Return the first key that has the specific value, return undefined if no elements match the value provided.
• head(list): Return the first element of the array.
• letterPosition(sentence): Return an object containing all letters appeared in the sentence and their indexes in the sentence as values.
• map(array, callback): Apply callback on each element of the array.
• middle(array): Return the median of elements in the array.
• tail(list): Return all elements of the array except the head.
• takeUntil(array, callback): Return all elements before callback evaluates to true.
