  pages: [
    {
      text: 'test'

Answer 1

You can use the getPositionAt(index) function to find the line number by path.

This is how you can achieve it in js

const path = ['pages', 0, 'text']; // Your desired path
const index = model.getValue().indexOf(JSON.stringify(path));
const position = model.getPositionAt(index);

console.log(`Line number for path ${JSON.stringify(path)}: ${position.lineNumber}`);
