The React Native DevTools were just announced at React Universe conf. You can’t use them yet, but if we all visualize using them, we can help manifest them into existence sooner. I learned that from The Secret.

Pop Quiz: Answer

let i = 0
function x() {
i++
return 10
}
i += x()
console.log(i) // ?
The answer is 10. Here’s how it works.
For clarity, we can refactor i += x() to be i = i + x(). From there, the interpreter begins evaluating our code. Before it evaluates the function invocation, it seems that i evaluates to 0, so now our code is i = 0 + x(). The invocation of x returns 10, so now it’s i = 0 + 10, which gives us i = 10.
Note that if you swap the order of i and x() like i = x() + i you get a different value - 🫂.

let i = 0
function x() {
i++
return 10
}
i += x()
console.log(i) // ?
答案是“10”。这是它的工作原理。
为了清楚起见，我们可以将 i += x() 重构为 i = i + x()。从那里，解释器开始评估我们的代码。在计算函数调用之前，“i”的计算结果似乎是“0”，所以现在我们的代码是“i = 0 + x()”。调用“x”返回“10”，所以现在是“i = 0 + 10”，这给了我们“i = 10”。
请注意，如果您交换“i”和“x()”的顺序，例如“i = x() + i”，您会得到不同的值 - 🫂。
