Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): Takes in two arrays and console.log a pass or fail message to indicate whether they are equal or not. Requires eqArrays.
• assertEqual(actual, expected): Takes in two values and console.log a pass or fail message to indicate whether they are equal or not.
• assertObjectsEqual(actual, expected): Takes in two objects and console.log a pass or fail message to indicate whether they are equal or not. Requires eqObjects.
• countLetters(string): Takes in a string and returns a count of each letter in the string.
• countOnly(allItems, itemsToCount): Takes in an array of items and an object of items to count. Returns an object containing the counts.
• eqArrays(array1, array2): Takes in two arrays and returns true or false based on a match.
• eqObjects(object1, object2): Takes in two objects and returns true or false based on if the objects have identical keys with identical values.
• findKey(object, callback): Takes in an object and a callback. Returns the first key in the object that received truthy from the callback.
• findKeyByValue(object, value): Takes in an object and value and returns the first key that contains that value.
• flatten(sourceArray): Takes in an array including nested arrays and returns a single level array.
• head(inputArray): Takes in an array and returns the first item in the array.
• letterPositions(sentence): Takes in a string and returns all the indices in the string where each character is found.
• map(array, callback): Takes in an array and a callback and loops through the array performing the callback on each on each element. Returns an array of the results.
• middle(array): Takes in an array and returns the middle items as an array. One or two items returns empty. Even number of items returns both middle.
• tail(array): Takes in an array and returns all items except for the first.
• takeUntil(array, callback): Takes in an array and a callback, collects items from the array until the callback returns truthy. Returns an array of the collected items.
• without(source, itemsToRemove): Takes in two arrays and returns a new array made of the source without the unwanted items.
