Documentation

The following functions are currently implemented:

• assertArraysEqual: with help of eqArrays function will log to the console a message whether or not two arrays are equal
• asserEqual: logs a message to the console whether or not two values are equal
• assertObjectsEqual: with help of eqObjects logs a message to the console whether or not two objects are equal
• countLetters: counts how many letters are in a given string (less spaces)
• countOnly: counts how many times a specific value shows up in an array of strings
• eqArrays: compares two arrays and returns whether or not they are strictly equal
• eqObjects: compares two objects and returns whether or not they are equal
• findKey: takes in an object and a callback and return the first key for which the callback returns a truthy value. If no key is found, returns undefined
• findKeyByValue: with a given value returns the first key where this value is found, if not undefined
• flatten: takes in an array with nested arrays, and returns a flattened array
• head: takes in an array and returns the first value of an array, if the array is empty returns undefined
• letterPositions: takes in a string and returns all the indices where each character is found (less spaces)
• map: takes in an array and callback and implement callback on the given array
• middle: takes in an array and returns the value at the middle index. If it is even, returns middle 2 values
• tail: takes in an array and returns the array less the first value
• takeUntil: takes in an array and callback and returns a slice of the array with elements taken from the beginning, until the callback returns a truthy value
• without: takes in two arrays and will return the first array less any values in the second
