Documentation

The following functions are currently implemented:

• assertArraysEqualTest((...):) takes 2 arrays as parameters, actual and expected. Prints assertion message based on if it's true or false.
• assertEqualTest(...): takes 2 primitive parameters, actual and expected. Prints assertion message based on if it's true or false.
• eqArrays(...): takes 2 arrays as parameters. Returns true if the arrays are similar.
• assertArraysEquals(...): takes 2 arrays as parameters, actual and expected. Prints assertion message based on if it's true or false.
• assertEqual(...): takes 2 primitive parameters, actual and expected. Prints assertion message based on if it's true or false.
• assertObjectsEqual(...): takes 2 objects as parameters, actual and expected. Prints assertion messaged based on if it's true or false.
• countLetters(...): takes a string as a parameter. Returns an object that shows how much times each letter appears in the input string,
• countOnly(...): takes 2 arrays as parameters. Returns true if the arrays are similar.
• countOnly(...): takes 2 parameters, a list of strings, and a string. Returns an object that shows how many times a string appeared in the list.
• eqObjects(...): takes 2 objects as parameters. Returns true if the arrays are similar.
• findKey(...): takes an object and a function as parameters. Returns the first key based on the given value.
• findKeyByValue(...): takes an object and a value as parameters. Returns the first key based on the given value.
• flatten(...): takes an array as parameter. Returns the sum of the array.
• head(...): takes an array as parameter. Returns the first element in the array.
• letterPositions(...): takes a string as a parameter. Returns an object showing how many times each letter appears in the string.
• map(...): takes an array and a callback function as parameters. Modifies each element in the array based on a callback function.
• middle(...): takes an array as parameter. Returns middle element as an array. If the length is equal, returns 2 middle elements in an array.
• tail(...): takes an array as a parameter. Returns everything but the first element in an array.
• takeUntil(...): takes an array and a callback function as parameters. Returns every element in the input array up until the given value. Returns a new array.
• without(...): takes an array and value as parameters. Returns a new array excluding the value.
