Documentation

The following functions are currently implemented:

• countLetters(string): Takes in a string and returns the total of each letter in that string
• countOnly(array, object): Takes an array of strings and an object of items to count, then returns the total for the specified subset of those items
• eqArrays(array1, array2): compares two arrays for equality
• eqObjects(object1, object2): compares two objects for equality
• findKey(object, callback): Takes two arguments, an object and a callback, then returns the first truthy key, or undefined if no key is found
• findKeyByValue(object, string): Takes in an object and a value and returns the matching key
• flatten(array): Takes an array of mixed elements and nested arrays as argument and returns it as a single flattened array
• head(array): Takes in an array and returns the first element of the array
• letterPositions(string): Takes in a string and returns the indexed positions of each occurrence of each letter in the string
• map(array, callback): Takes in an array and a callback function as arguments, applies the callback to each element of the array, then returns a new array with the results
• middle(array): Takes an array and returns the middle element(s) as a new array
• tail(array): Takes an array and returns every element except the first one
• takeUntil(array, callback): Takes an array and a callback and returns a new array with elements taken from the beginning until the callback condition is met, or the entire array if the condition is never met
• without(array1, array2): Takes two arrays and filters out the elements in the second array from the first array, then returns a new array
