取消循环

Question

每当我运行这个片段时：

let longString = 0;
let fact = 6;
const lettersLeft = ["abcde"]
const select = lettersLeft;
let j = 1
while (j <= fact, j=j+1) {
longString += select;
}
console.log(longString);

它使我的应用程序崩溃。我在想它是在拼命奔跑，或者它读不懂什么。我该如何解决这个问题，因为这对我的代码非常重要。

只要对while表达式稍作更改，就可以使其工作：

let longString = 0;
let fact = 6;
const lettersLeft = ["abcde"],
select = lettersLeft;
let j = 1;
while (j++ <= fact)
longString += select;
console.log(longString);
