--description--

The innerText property controls the text that appears in an HTML element. For example:

const info = document.querySelector("#info");
info.innerText = "Hello World";

This code would change the element assigned to the div variable to have the text Hello World.

When a player clicks your Go to store button, you want to change the buttons and text. Remove the code inside the goStore function and add a line that updates the text of button1 to say Buy 10 health (10 gold).

--hints--

You should not have a console.log("Going to store."); line in your code.

assert.notMatch(code, /console.log\(('|")Going to store\.\1\)/);

You should use dot notation to access the innerText property of button1.

assert.match(code, /button1\.innerText/);

You should not use let or const to access the innerText property of button1.

assert.notMatch(code, /(let|const)\s+button1.innerText/);

You should update the innerText property of button1 to be Buy 10 health (10 gold).

assert.match(code, /button1\.innerText\s*=\s*('|")Buy 10 health \(10 gold\)\1/);

You should update the innerText property within your goStore function.

assert.match(goStore.toString(), /button1\.innerText\s*=\s*('|")Buy 10 health \(10 gold\)\1/);
