为什么要使用“var me=this”这样的写法

只为压缩。

function doA() {
    var me = this;
    
    me.a();
    me.b();
    me.c();
    me.d();
}
function doB() {
    this.a();
    this.b();
    this.c();
    this.d();
}

压缩后:

function doA(){var a=this;a.a();a.b();a.c();a.d()};
function doB(){this.a();this.b();this.c();this.d()};
