Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(): The function for asserting that two arrays are equal.
• assertEqual(): The function compares the two values it takes in and print out a message telling us if they match or not, this does not include arrays or objects.
• assertObjectsEqual(): The function will take in two objects and console.log an appropriate message to the console.
• countLetters(): The function takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(): The function will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• eqArrays(): The function compares two arrays for a perfect match.
• eqObjects(): The function will take in two objects and returns true or false, based on a perfect match.
• findKey(): The function takes in an object and a callback. It scans the object and return the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue(): The function takes in an object and a value. It scans the object and return the first key which contains the given value. If no key with that given value is found, then it returns undefined.
• head(): The function retrieves the first element from an array

• letterPositions(): The function will return all the indices (zero-based positions) in the string where each character is found.

• map(): The function will take in two arguments, an array to map and a callback function. The function will then return a new array based on the results of the callback function.

• middle(): The function returns an array with only the middle element(s) of the provided array.
• tail(): The function returns every element except the head (first element) of the array.
• takeUntil(): The function will return a slice of the array with elements taken from the beginning. It should keep going until the callback returns a truthy value.
• without(): The function returns a new array with only those elements from source array that are not present in the itemsToRemove array.
