[英]typeof(1) prints “Number” to the console, but when i ask if typeof(1) == Number, it prints out false, why?
typeof(1) 將“Number”打印到控制台，但是當我詢問 typeof(1) == Number 時，它打印出 false，為什么？
console.log(typeof(1));
//Number
console.log(typeof(1) == Number);
//false
typeof返回一個字符串，所以檢查一個
typeof(1) == 'number' // true
// or better without ( ), since you don't need them here
typeof 1 == 'number' // true
應該沒問題。 關於typeof的更多背景信息： https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/typeof
