JavaScript RangeError – 重复次数必须小于无穷大

如果String.prototype.repeat()方法的传递参数为无穷大，则此 JavaScript 异常重复计数必须小于无穷大。

信息：

RangeError: argument out of range (Edge)
RangeError: repeat count must be less than infinity and not 
            overflow maximum string size (Firefox)
RangeError: Invalid count value (Chrome)

错误类型：

RangeError

错误原因：传递的String.prototype.repeat()方法的count参数要么小于0，要么大于无穷大。

例1：本例中传递的参数是4，所以没有发生错误。

                try {
                    "GFG".repeat(4);
                    el_down.innerHTML = "'Repeat count " +
                      "must be less than infinity' " +
                      "error has not occurred";
                } catch (e) {
                    el_down.innerHTML = "'Repeat count " +
                      "must be less than infinity' " + 
                      "error has occurred";
                }
            }
        
    

输出：

例2：在这个例子中，传递的参数是 2 ³² ，所以出现了错误，
