Install dependencies:

npm install

Start the server:

npm run dev

This joke project came out of:

• Frustration with a test that keeps on failing
• A bet with a friend that this will work

Enter the expected input and output pairs and click "Generate".

It will try to randomly generate a JavaScript function until by chance it finds a function that matches all specified test cases.

Note, the performance is horrible for all but trivial cases.

The "Iteration limit" parameter determines how many times it tries to generate

The "Soft token count limit" is responsible for making the random generator more conservative (i.e avoid if statements and declaring new variables) as the limit is approaching.

The random generator is implemented as simplified JavaScript syntax tree with weights attached to branches of the tree.

See syntaxTree variable in ./src/generator/syntax.ts

No machine learning or fancy AI magic is used - pure randomness (it's about as efficient as Bogosort)
