Variables are data containers which, as the name implies, can get their data changed through assignment operations. If you want to store some data, you'll use a variable. The basic syntax is:
var/myVariable = initialValue
var is the keyword telling the compiler we're defining a new variable.
myVariable is the variable's name, which cannot be a reserved word like
var as we said previously.
= initialValue is used to assign an initial value to the variable. This is optional, and if omitted, the variable's value will be
null, a special value that means the variable holds nothing.
A key difference in other languages, like C, is that primitive variables don't need the user to define their type, which means you can do
var/myVar = "Hello World"
myVar = 1
without any sort of error. Even though this will work with any sort of var type, we will see futher on that it can cause issues when our variables hold objects and we try to access its methods or such, but we'll expand on this later.
Try using a combination of a variable and a
world << "x"statement to output the text
"DMBE"to the chat window.
