js报错Uncaught SyntaxError: Illegal return statement

let arr = ['a','b','c']for( let i=0;i<=arr.length;i++){if (i ==2 ){console.log(arr[i])return  // 报错 Uncaught SyntaxError: Illegal return statement，只能在function中使用} }

 只能在函数中使用return

function run() {let a = 1if (a == 1) {return}console.log(2); // 不会输出，return中断执行后面代码
}
