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

Documentation

The following functions are currently implemented:

• function1(head): Takes the first item in an array
• function2(tail): Removes the first item from an array and returns the rest of the array
• function3(middle): Returns the middle item in an array (or two items for an array with an even number of items)
• function4(eqArrays): Returns true if two arrays are equal in length and values
• function5(countLetters): Given a letter, it counts the number of that character in a given string
• function6(assertArraysEqual): Returns assertion passed if eqArrays returns true, and assertion failed if they are not
• function7(assertEqual): Compares an actual and expected result and returns assertion passed if they are equal and failed otherwise
• function8(assertObjectsEqual): Compares two objects using eqObjects and if they are equal returns assertion passed, otherwise assertion failed
• function9(countOnly): When given an input, it counts the number of instances of that input in an array
• function10(eqObjects): Compares two objects and returns true if they are the same and false otherwise
• function11(findKey): When given a value and an object it returns the first truthy key
• function12(findKeyByValue): When given a specific value, returns that key
• function13(flatten): Removes sub-arrays from an array and lists all the values in their original order in a new array
• function14(letterPositions): Return the index number of a given character in a given string
• function15(map): Given an array and a callback function, map returns a new array based on the callback results

• function16(takeUntil): Given an array and a callback function, take until returns a new array which includes the results of the starting array up to the point indicated by the callback
