DECLARING VARIABLES

In HookScript, you declare variables using the var keyword:

var name = "hook"

Variables do not need to be assigned a value immediately. If a value is not assigned, the variable will have a value of NULL (more on NULL later)

var name
print(name) // NULL

To assign a new value to an existing variable, use the assignment operator ( = )

var name = "hook"
name = "script"

HookScript is a gradually typed language, which means you can specify types for variables to improve type checking and reduce runtime errors. For example, if I want a variable to only hold int types, I would specify the type after the variable name:

var x int = 10
x = "a string" // will throw a type check error

You can use the gradually typed feature of the language to improve the developer experience by determining how explicit you want to be when writing your code. In the example below, the variable x can hold any type since a type was not provided when x was declared:

var x = 10 // x is int type
x = "Hello World" // x is text type
x = true // x is bool type
x = 3.14 // x is float type
