javascript - “未定义 setTimeout”

Question

有了一些基本的代码，我试着看看为什么有人的简单代码不起作用

它给我的错误是“未定义 setTimeout（第 15 行，第 1 列）

setTimeout(function() {

  let time = new Date().getHours();

  /**
   * this script is to use per hour with 8 images, to change this to minutes, seconds or anithing, change time value from getHours to getMinutes or what you like, even can change it to days if yu want
   */
  if (time == 4 || time == 12 || time == 20) { //if hour equals 4:XX, 12:XX or 20:XX
    return 1; //opacity value = 1
  } else return 0; //if not, opacity equals 0 (transparent)

}, 36000); //36000 are the seconds

在我尝试了许多小调整后，我决定来这里寻求帮助。
