[] usually containing an index for an array/object, with this index number you can access the particiular element in the array/onject void means nothing, none, empty, trash.... it just means there is no return value of a function/method. console.writeline will add an newline char to the end of the given string. So it will write a full valid line console.write will not...it just append the given string

well, just go ahead with the tutorial and you will learn. in short terms: functions / methods are used to call code that is used several times. those calls can give you an result of eg an calculation, or you just printed out something. For the print you can use void as return value but for the calculation you want to get the result Array is an variable type or container which can include more than only one value. Imagine it as a list of values. Each list position do have a index number. With this index number you can acces the item.
