JavaScript 中分号是可选的。 但是，我可以省略 for 循环中的分号吗？

Question

Semicolon is optional in JavaScript. However, could I omit the semicolons in the for loop? For example:

for (let i = 0 i < arr.length i++) {
    console.log(arr[i])
}

I'm new to JavaScript, I'm coming from C and C++ where semicolon is a must.

Answer 1

Semicolons are used when you have more than one statements. If you have only one statement in for loop, you don't need to put semicolon.
