Variables
Access variables
Access the value of a variable by its variable name.
a + b
If the value of the variable is a context, a context entry can be accessed by its key.
a.b
tip
Use a null-check if the variable can be null or is optional.
a != null and a.b > 10
Escape variable names
The name of a variable can be any alphanumeric string including _ (an underscore). For a
combination of words, it is recommended to use camelCase or the snake_case format.
If a variable name or context key contains any special character (e.g. whitespace, dash, etc.,) the name can be placed in single backticks (e.g. `foo bar`).
`first name`
`tracking-id`
order.`total price`
