Variables

You must know that a variable is unique to a user. If we restart the script with another user (that is, with another username), the values ​​will be different.

A local variable

Creating a variable is very simple.

name = 'ana'

In a function:

start() {
    name = 'ana'
}

This variable is local to the function. When this function is finished, the variables are deleted to free the memory.

Global variable

A global variable can be used throughout the script. It belongs to the user. A global variable is prefixed with $

$name = '' // initialization

start() {
    $name = 'ana'
}

Display the variable in an output text

We can insert a variable into an output text:

$name = 'ana'

start() {
   > Hello { $name }
}
