如何在Javascript中横向打印？

var str = "Hello, World!";
for (var i = 0; i < str.length; i++) {
  console.log(str.charAt(i));
}

var arr = [1, 2, 3, 4, 5];
arr.forEach(function(element) {
  console.log(element);
});

var arr = [1, 2, 3, 4, 5];
for (var element of arr) {
  console.log(element);
}

var str = "Hello, World!";
var chars = str.split('');
console.log(chars.join('\n'));
