East Language DSL FAQs

Question 1

Can East interact with standard JavaScript functions?

Accepted Answer

Yes, East uses 'Platform Effects' via East.platform() or East.asyncPlatform() to define signatures for external TypeScript functions that can be called from within East code.

Question 2

What is the East programming language?

Accepted Answer

East is a statically typed, expression-based programming language embedded in TypeScript. It is used to write logic using a fluent API that can be compiled into a portable Intermediate Representation (IR).

Question 3

How does East handle type safety?

Accepted Answer

East features a strict type system including primitives (Integer, Float, String), collections (Array, Set, Dict), and compound types (Struct, Variant, Recursive) to ensure code correctness before compilation.

Question 4

What is the purpose of East IR?

Accepted Answer

The Intermediate Representation (IR) allows East programs to be serialized into JSON and executed on different platforms or environments without needing the original source code.

Question 5

When should I use East instead of regular TypeScript?

Accepted Answer

Use East when you need to define logic that must be serialized, sent over a network, or executed in a controlled environment where standard JS execution might be too broad or unsafe.
