Google 很重视代码风格的一致性，而且还公开过一份 JavaScript 代码风格指南： Google JavaScript Style Guide，现在它们又发布了一个工具来帮助你检查 JavaScript 代码是否严格遵循了 Google JavaScript Style Guide ：Closure Linter。
假设你有以下代码：
在命令行下运行 gjslint –strict fixme.js 之后，就会出现下面的结果：
这个工具甚至可以帮你自动修复一些错误，运行 fixjsstyle –strict fixme.js 即可。（注意：不一定可以修复全部错误）
假设你有以下代码：
var x = 10
var y=20;
for(var i = 0;i < 10; i++ ) {
x += i;
y -= i;
}
var z = [10, 20,];
x = y + z[0]
+ 10;
在命令行下运行 gjslint –strict fixme.js 之后，就会出现下面的结果：
