Call it:

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

Documentation

The following functions are currently implemented:

• 'head' : Returns the first element of an array.
• 'tail' : Returns all elements indexed after the first element 1, 2...
• 'middle' : Returns the element indexed in the middle of an array, if even length array is encountered it returns the two middle elements.
• 'assertArraysEqual' : An asserting function that logs a boolean as to whether our actual vs expected array arguments are strictly equal.
• 'assertEqual' : Returns a boolean comparing if our actual argument is strictly equal to our expected argument.
• 'assertObjectsEqual' : Returns a boolean comparing if two objects are strictly equal.
• 'countLetters' : Returns a count of each of the letters in a string.
• 'countOnly' : Function which accepts 2 arguments, an array of strings and object of things we want to count in that array. It returns an object detailing the resulting count.
• 'eqArrays' : Compares two arrays and returns a boolean as to their strict equality.
• 'eqObjects' : Compares to objects and returns a boolean as to their strict equality.
• 'findKey' : Accepts an object and a function. Returns the first key from the object whose value makes the function return true.
• 'findKeyByValue' : Accepts an object and a value, returns the first key which contains the given value.
• 'letterPositions' : Returns all the indices in a string where each letter occurs.
• 'map' : Performs a given function on each element of an array, and returns the results in a new array.
• 'takeUntil' : Accepts an array and a function. Creates a new array, iterating through and populating it with every element in the source array until the given callback function evaluates to true.
• 'without' : Accepts two arrays as arguments, source and toRemove. Returns a new array populated with all the elements in the source that did not match elements in the toRemove array.
