const _ = require('@mike.simnes/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arrayOne, arrayTwo): function to display the appropriate message to the console if two arrays match or not leveraging existing eqArrays function.
• assertEqual(actual, expected): logs a clear message to the console whether actual === expected or not.
• asserObjectsEqual(object1, object2): leverages eqObjects and eqArrays and returns a clear message to the console if they match or not.
• countLetters(string): takes in a string or several strings adn returns the count of letters excluding whitespaces.
• countOnly(allItems, itemsToCount): This function takes in a collection of allItems and return counts for items selected in itemsToCount.
• eqArrays(arrayOne, arrayTwo): Compares two arrays and returns true or false if they match or not.
• eqObjects(objectOne, objectTwo): Compares objects to see if they are equal, works with nested objects and arrays.
• findKey(object, callback): Takes in an object and a callback, returns the key according to the callback passed in.
• findKeyByValue(object, value): Finds the key of the corresponding value passed in as an argument.
• flatten(array): Function to take in an array or array of nested arrays and return a flattened array. using recursion to find the depth of the array and then flatmap to flatten the array to the given depth.
• head(array): Returns the first item of an array.
• letterPositions(string): Takes in a string and returns an object with the letters and positions of each letter.
• map(array, callback): Returns a new array based on the results of the callback function.
• middle(array): Returns middle element if array length is odd, returns middle two items if length is even.
• tail(array): Returns a new array containing only the tail of the original array.
• takeUntil(array, callback): Returns a slice of the array from the beginning until the callback returns a truthy value.
• without(source, itemsToRemove)': Returns a subset of the first argument 'source' array, removing unwanted elements from the second arg 'itemsToRmemove'.
