Documentation

The following functions are currently implemented:

• assertArraysEqual(actual,expected): Takes in two arrays and asserts if they are equal or not
• assertEqual(actual, expected): Takes in two values and asserts if they are equal
• eqArray(x, y): Takes in two arrays and compares them
• assertObjectEqual(actual, expected): Takes in two objects and asserts if they are equal
• countLetters(sentence): Takes in an array of strings and returns an object with the letter count for each letter
• countOnly(allItems,ItemsToCount): Takes in an array of strings and returns an object with the appropriate counts.
• eqObjects(Object1, Object2): Takes in two objects compares them
• findKey(obj, callback): Takes in an object and a callback. It will traverse the object and return the first key for which the callback returns a truthy value. If no key is found, then it will return undefined.
• findKeyByValue(obj, value): Takes in an object and a value. Scan an object and return the first key which returns the given value
• head(array): Returns the first element of an array
• letterPositions(sentence): Returns all the indicies in the string where each character is found.
• map(array, callback): Takes in an array and a callback and returns a new array after using the callback function on each element of the array
• middle(array): Takes in an array and returns the middle index. If there is two numbers, returns the middle two indexes.
• tail(array): Retrieves all elements of an array except the first one.
• takeUntil(array,callback): Takes in an array and returns a slice of the array taken from the beginning
• without(source, itemsToRemove): Takes in an array and itemsToRemove returning a new array with the items removed
