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

Documentation

The following functions are currently implemented:

• assertArraysEqual(): Compares two arrays and print out a message alerting us if they are strictly equal or not.
• assertEqual(): Compares two values and print out a message alerting us if they are strictly equal or not.
• assertObjectsEqual(): Compares two objects and print out a message alerting us if they are strictly equal or not.
• countLetters(): Takes in a sentence (as a string) and then returns a count of each of the letters in that sentence.
• countOnly(): Takes in a collection of items and returns counts for a specific subset of those items.
• eqArrays(): Compares two arrays and returns true or false, if they are strictly equal or not.
• eqObject(): Takes in two objects and returns true or false, if they are strictly equal or not.
• findKey(): Takes in an object and a callback, scans the object and return the first key for which the callback returns a truthy value. If no key is found, it returns undefined.
• findKeyByValue(): Searches for a key on an object where its value matches a given value.
• head(): Retrieves the first element from a given array.
• letterPosition(): Returns all the indices (zero-based positions) in the string where each character is found.
• map(): Takes in an array and a callback function and returns a new array base on the results of the given callback function.
• middle(): Takes in an array and returns the middle-most element(s) of a given array.
• tail(): Retrieves the tail which is every element except the head (first element) of a given array.
• takeUntil(): Takes in an array and a callback function and returns a slice of the array with elements taken from the beginning until the callback returns a truthy value.
• without(): Filters out given elements form a given array.
