How does Text Interpolation achieve reactivity? #10837

I'm not sure how you are interested in text interpolation specifically, since it works like all other reactivity in the template. Conceptually, the component executes the render function in (something like a)
Since this is a complex process there is not one point/function to just set a breakpoint in, so you would need to explain what part of the process you are interested in if I were to give you more guidance. |

To debug how text interpolation achieves reactivity in the code you provided, you can set a breakpoint inside the render function. This is where the DOM elements are created based on the reactive state (counter) and where the text interpolation (count: ${counter.value}) occurs. const render = () => {
debugger; // Set breakpoint here
return h("div", { class: "app" }, [
h("h2", { class: "title" }, `count: ${counter.value}`),
h("button", { onclick: increment }, "+"),
h("button", { onclick: decrement }, "-")
]);
}; With the breakpoint set inside the render function, you'll be able to inspect how the reactive state (counter.value) is accessed and how changes to it trigger updates to the DOM elements. |

I want to debug the code above to see how Text Interpolation achieves reactivity, but I have been trying for a while and can't find the crucial function. Can you tell me in which function I should set a breakpoint?
Thank you!
