Tridash is a programming language which aims to make the development of interactive applications easier and less error-prone.

How’s it Different

What sets Tridash apart from the popular languages of today is that it is designed from the ground up for developing applications which respond to user interaction and events, whereas most programming languages, particularly imperative programming languages are originally designed for developing batch-style applications which perform their task and then exit without interacting with the user. As a result developing interactive applications with these languages, is difficult and prone to bugs.

In Tridash an application is composed of a set of stateful computational components called nodes. Each node has a particular value, which is computed from a function of one or more dependency nodes. When the values of a node’s dependency nodes changes, the node’s value is automatically recomputed. Nodes can either be purely computational components or can be bound to the state of a user interface element, the network or the file system. For example a node can be bound to the value of a text field UI element.

With Tridash you can focus on the core logic of your application code, by expressing the application state as a set of dependencies between components. This is contrary to the approach taken by most languages where your application is expressed as a linear sequence of instructions, in which it is up to the programmer to manually manage the application state correctly.
