Call it:

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

Documentation

The following functions are currently implemented:

• head(...): returns the first element in an array
• tail(...): takes off the head of array and returns the rest
• middle(...): returns value in the middle of array
• assertArraysEqual(...) : take in two arrays and console.log an appropriate message to the console.
• assertEqual(...) : Prints "ASSERTION PASSED" or "ASSERTION FAILED" based on if results is true or false
• eqObjects(...): takes in two objects and returns true or false, based on a perfect match.
• assertObjectEqual(...) : which will take in two objects and console.log an appropriate message to the console.
• eqArrays(...) : takes in two arrays and returns true or false, based on a perfect match.
• countLetters(...) : takes in a string and returns an object with each letter that appears as a key and the number of times it appears in the string as a value.
• countOnly(...) : take in a collection of items and return counts for a specific subset of those items
• findKey(...) : which takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• findKeyByValue(...) : takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• flatten(...) : take in an array of arrays and return a "flattened" version of the array.
• letterPositions,
• map(...) : take in two arguments: an array to map + callback function. The map function will return a new array based on the results of the callback function.
• takeUntil(...) : return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• without(...) : takes in a source array and a itemsToRemove array. Returns a new array with only those elements from source that are not present in the itemsToRemove array.
