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

Documentation

The following functions are currently implemented:

• assertEqual: Compares two values and tells us whether they match or not.
• eqArrays: Checks whether two arrays are equal or not.
• assertArraysEqual: Asserts whether two arrays are equal or not.
• eqObjects: Checks whether two objects are equal or not.
• assertObjectsEqual: Asserts whether two objects are equal or not.
• head: Returns the first item of an array.
• tail: Returns an array minus the first element.
• middle: Returns the middle-most element/elements of an array.
• flatten: When given an array containing elements (including nested arrays) it returns a "flattened" version of the array.
• countOnly: When given an array and an object, it returns an object containing counts of everything that the input object listed.
• countLetters: Returns the count of each letter/character in a given string.
• letterPositions: Returns all the indices of every letter/character in a given string.
• findKey: Takes in an object and a callback function. It scans the object and returns the first key for which the callback function returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue: Takes in an object and a value. Scans the object and returns the first key which contains the given value. If no key with the said value is found, then it returns undefined. takeUntil: Keeps collecting items from a given array until the callback function provided, returns a truthy value. map: Takes in two arguments: An array to map and a callback function. Returns a new array based on the results of the callback function. without: Returns a subset of a given array without the unwanted elements.
