【备忘录】javascript字符串翻转

var fruit = "apple banana pear";
var arr = fruit.split(' ');
for (var i = 0; i < arr.length; i++) {
      arr[i] = arr[i].split('').reverse().join('');
}
var newfruit = arr.join(' '); // 1

var newfruit2 = fruit.replace(/\s/g, '.').split('').reverse().join('').replace(/\./g, ' '); // 2

// python: ' '.join(fruit[::-1].split(' ')[::-1])
