Documentation

The following functions are currently implemented:

• assertArraysEqual(array1,array2): it prints message to console that whether two arrays are equal or not.
• assertEqual(actual, expected): it prints to console, if actual is equal to expected. It works on primitive data types only.
• assertObjectsEqual(actualObj, expectedObj): this function takes in 2 objects and returns true if they are equal and false otherwise.
• countLetters(string): this function takes in a sentence and returns a count of each of the letters in the sentence.
• countOnly(allItems, itemsToCount): this function takes in a collection of items and returns a specific subset of those items.
• eqArrays(array1,array2): this function returns true if two arrays are exact match.
• eqObjects(object1, object2): it takes two objects and returns true if both objects have identical keys with identical values otherwise false.
• findKey(object, callback): it scans the object and returns the first key for which the callback returns a truthy value. if no key is found, it returns undefined.
• findKeyByValue(object,value): this function takes in an object and a value. It returns the first key that corresponds to the value.
• flatten(arrayOfNestedArrays): this function takes in an array that contains elements including nested array of elements and returns a flattened version of the array (one level deep only).
• head(array): this function returns first element of the array.
• index(string).letter: this function takes in a string and returns all indices of letter positions in the string.
• map(array, callback): this function takes in an array and a callback function. It returns a new array based on the results of the callback on each item in the array.
• middle(array): it returns the middle most element of the array.
• tail(array): it returns the last / tail element of an array.
• takeUntil(array, callback): this function takes in an array and callback. It returns a slice of the array based on the criteria specified in the callback.
• without(sourceArray, itemsToRemoveArray): it returns only the items from the source array that are not in the itemsToRemove array.
