for(var i=0;i=bullets.length;i++){

this.ctx.drawImage(bullet,bullets[i][0]+55,bullets[i][1]); 这里报错

}变为

}

扩展资料：

Javascript被归类为直译语言，因为主流的引擎都是每次运行时加载代码并解译。V8是将所有代码解译后再开始运行，其他引擎则是逐行解译（SpiderMonkey会将解译过的指令暂存，以提高性能，称为实时编译），但由于V8的核心部分多数用Javascript撰写（而SpiderMonkey是用C++），因此在不同的测试上，两者性能互有优劣。

与其相对应的是编译语言，例如C语言，以编译语言编写的程序在运行之前，必须经过编译，将代码编译为机器码，再加以运行。
