Data types
AEL (Expression language) was created to process data and turn it into presentable responses that will be valuable to the bot's users. This data can be obtained in different ways: it can be a result of NLU recognition (an intent or a variable), a response from an API integration, or a value previously stored in Memory.
Each piece of such data has its own type.
Each type of data has its own purpose and its own methods that can be used to process it. For example, any plain text will have a data type of string so you can perform operations relevant to texts (like joining them together), and any number will have a data type of number so you can, for example, perform arithmetical operations on them.
