要按首字母对JavaScript数组进行排序,可以使用sort()方法和localeCompare()函数。首先,使用sort()方法对数组进行排序,传入一个比较函数作为参数。在比较函数中,使用localeCompare()函数对元素的name属性进行比较,以实现按首字母升序排序。以下是一个示例代码:
```javascript
// 根据英文首字母进行排序
arr1.sort(function(a, b) {
return (a.name + '').localeCompare(b.name + '');
});
console.log(arr1);
```
其中,arr1是待排序的数组,name是数组元素的属性。通过这段代码,数组arr1将按照元素的name属性的首字母进行升序排序。\[1\]\[2\]
