Answer 3

Javascript doesn't have an integer type, but a Number type.

Answer 4

Why one is a method (toString) and another is a function (parceInt) ?

Answer 5

string to integer use: Number(//your argument here);
integer to string use: String(//your argument here);
for the case of string to integer Number() will convert a number with quotes to a number without quotes (of type number) but if your argument is a float you have to use these:
Math.ceil(argument);// to always round up to highest value.
Math.floor(argument);// to always round down to lowest integer
Math.round(argument);// to round up or down

Answer 6

The toString() method belongs to the Object class which Number inherits from, as do all JavaScript classes.
