Se supone que mi código actualiza "nivel" al valor de "level_num", pero en su lugar, sigue devolviendo 0.

 function find_level() { let level_num = 0; document.querySelector("#easy").onclick = () => { document.querySelector("h3").innerHTML = `You chose Easy. Good Luck!` level_num = 1; } document.querySelector("#medium").onclick = () => { document.querySelector("h3").innerHTML = `You chose Medium. Good Luck!` level_num = 2; } document.querySelector("#hard").onclick = () => { document.querySelector("h3").innerHTML = `You chose Hard. Good Luck!` level_num = 3; } return level_num; } document.addEventListener('DOMContentLoaded', function() { let level = find_level(); document.querySelector("h1").innerHTML = `You chose ${level}. Good Luck!` })
