ajax 回调结束时 .bind(this) 的目的是什么

Javascript
function User() {
  this.name = 'John Doe';
}
User.prototype.getUserInfo = function() {
  $.Ajax({
    url: 'https://api.example.com/user',
    success: function(response) {
      console.log('User info:', response);
      console.log('Name:', this.name); // 此处无法访问到 this.name
    }.bind(this),
    error: function() {
      console.log('FAIled to get user info');
    }
  });
};
var user = new User();
user.getUserInfo();
