Variables

In Abstra, you can create variables to help you manage your application state. You can create or delete variables at the variables section of the left sidebar.
Local and Global variables management at the left sidebar
Variables can be Local or Global. Global variables can be accessed or modified in any Page or Component of your application. Local variables are bound to Pages or Components, so they can only be accessed and modified inside them.
You can configure a variable's name, type, default value and persistence.
As in math, variables are a "tool" that you can define a value to and reutilize it in multiple points of your app. Let's say I create a variable named bestBand, and give it the value Arctic Monkeys. So if I utilize my variable anywhere in my code it would represent Arctic Monkeys.
The text The best band in the world is {{ bestBand }} will be rendered as The best band in the world is Arctic Monkeys.
You can also change the value of your variable at any time in your application as you please, that way if you want that your variable to changes depending on the rules of your application, change them. You can read more about how to change a variable's value at the Set variable action section.
The bestBand example shows how to read a variable using Mustache notation but they can also be accessed using the Expression mode. Read more on how to use your variables at these sections.
Variable Types
Abstra comes with many different variable types:  
Text: any text value you may want to store, such as names, urls, and other textual information
Yes/No: any boolean values. For example you might want to store if a user has clicked a button
Number: any numerical values, decimal or integer
Image: the same as a text variable but it preview the result of the image URL
Component: a reference to a component
Icon: string with SVG path of an icon
Color: string with hex of a color
Datetime: string with timestamp of da datetime
Rich Text: string with rich text formatting
Array / List: when you want to store a list, for example the results of  a Checkbox with multiple answer allowed.
Object / Dictionary: when you have more complex variables and it can have fields inside. For example you can have a meeting object like the following:
Anything: a variable that accepts any of the other types above.
Table Types
When you have some hosted tables created, you can create variables with types according to them:
The first is typed as a single row of the table, so you can get auto suggestions for the complete row or each column:
The second is typed as a list of rows, just like the result of a Query, so you can get suggestions for the list, the size of the list, the first row and its columns: 
Variable Path
When using a composite type variable you may want to set/read just a specific field of it.
For this we have the variable path argument in most places where you use variables.
For example you have a variable obj:
You can set an input to bind itself to just that field:
