Promise如果一直没有resolve,await会一直等待吗?

代码如下,这种情况,是不是程序一直都在等待。

function foo(x) {
    return new Promise((resolve) => {
        if (x > 1) {
            resolve(11)
        }
    })
}

async function test() {
    let a = await foo(0)
    alert(a)
}

test()

会。所以会内存泄露。所以一定要保证 Promise 被 resolve 或 reject 了。
