The final step is to call the script to perform the conversion to words for you. To get a number converted to words you just need to call the function passing it the number you want to convert and the corresponding words will be returned. var words = toWords(num); i am doing applicati...
every(function(number) { return number > 0; }); console.log(allArePositive); // 输出 true,因为数组中所有数字都是正数 在上面的示例中,我们定义了一个名为allArePositive的变量来存储every()方法的返回值。我们通过传递一个测试函数来检查数组中的所有数字是否都是正数。由于数组中所有数字都是正数,所以...
