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

Documentation

The following functions are currently implemented:

• assertArraysEqual: takes 2 arrays and asserts whether the 2 arrays are equal.
• assertEqual: takes 2 primitive data types and asserts whether they are equal.
• assertObjectsEqual: takes 2 objects and asserts whether the 2 objects are equal
• countLetters: takes a string and returns an object with letters as the key and number of occurences as the value. does not count blank spaces.
• countOnly: takes an array and an object with boolean values. Returns an object with truthy valued keys and the number of occurences in the array. Does not contain a truthy key with zero occurences in the array.
• eqArrays: takes 2 arrays and checks whether the 2 arrays are equal .
• eqObjects: takes 2 objects and checks whether the 2 objects are equal .
• findKey: takes an object of objects and a function. Returns the first key of the object whose values satisfies the function.
• findKeyByValue: takes an object and a value. Returns the first key with the set value.
• flatten: takes a one level nested array and return a non-nested array, with every value "unnested".
• head: takes an array and returns the first value of the array.
• index: script with all the functions. Require this function in order to use every function.
• letterPositions: takes a string and returns an object with letters as the key and index of their position as the value. Blanks spaces are not included as keys.
• map: takes an array and a function. Returns an array with the function applied to each of the elements. Does not change the original array.
• middle: takes an array, and returns the middle value. If the length of the array is even, will return an array of the two middle values.
• tail: takes an array and returns an array without the first index. Does not change original array
• takeUntil: takes an array and a value. Returns an array with the inputted arrays indicies, up until the value. Will not include the value in the array. Does not change the original array.
• without: takes an array and a second array. Returns the first array without any of the values of the second array in it. Does not alter either inputted arrays.
