A constructor is a special method that builds the instance of an object when a new object is created.
Arrays are used to assign a series of elements of the same type in consecutive memory locations; to define a list of elements. They work similar to variables, except they contain multiple values at different indices.
The ternary operator is used to execute code based on the result of a binary condition. It takes in a binary condition as input, which makes it similar to an 'if-else' control flow block. It also, however, returns a value, behaving similar to a method.
