JavaScript 中的for in

    const jumpPermissionList = [".openadsdk.permission.TT_PANGOLIN", "com.hihonor.permission"]

   for (let x in jumpPermissionList) {
            console.log("for  x:",x)
            if (permission.includes(jumpPermissionList[x])) {
                jumpPermission = true
                console.log("includes:",jumpPermission)
            }
        }

 console.log("for  x:",x)
打印出来的x 居然不是子元素。而是子元素索引

这和python不太一样

Python打印出来是子元素
