+<p>O método <code><strong>Promise.resolve(value)</strong></code> retorna um objeto {{jsxref("Promise")}} que é resolvido com o valor passado. Se o valor for <em>thenable</em> (ex: tiver um método {{jsxref("Promise.then", "\"then\"")}}), a promise retornada irá "seguir" esse <em>thenable</em>, adotando seu estado final; se o valor for uma promise, o objeto será o resultado da chamada Promise.resolve; do contrário a promise será realizada com o valor.</p>
