Google Closure Tools〔Bolin, Michael, "Closure: The Definitive Guide", O'Reilly Media Inc., Sebastopol, CA, 2010〕 is a set of tools to help developers build rich web applications with JavaScript. It was developed by Google for use in their web applications such as Gmail, Google Docs and Google Maps.〔https://developers.google.com/closure/faq#gwt〕 ==Closure Compiler== The (Closure Compiler ) is a tool for making JavaScript download and run faster, at the expense of human readability. It does not compile from JavaScript to machine code, but rather compiles from JavaScript to more efficient JavaScript. It parses JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls. It supports transpiling some ECMAScript 6 code to ECMAScript 3, so that programmers can write JavaScript that uses those features, and run it in browsers or other environments that don't yet support them. (The (Traceur Compiler ) is another Google project that supports transpiling ES6 to ES3.) The compiler is provided in three ways: *Command-line: * *This Java application can be invoked from the command line, and passed the list of JS files to be compiled. *Interactive-way: * *(Closure Compiler service website ) provides a form for user to input a URL pointing a JavaScript source or input a JavaScript source in a textbox and the website will response with the ''optimized JavaScript'' on right side for user to copy. *HTTP POST API: * *(Closure Compiler server website ) is waiting HTTP POST with severals HTTP POST parameters, (see complete list ). One is ''js_code'' or ''code_url'' which contains the string of JavaScript to be optimized. In return to the HTTP POST, the optimized JavaScript code will be the response content of application/x-www-form-urlencoded. The Closure compiler also supports type checking via type annotations that must be written in JSDoc comments.〔https://developers.google.com/closure/compiler/docs/js-for-compiler〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Google Closure Tools」の詳細全文を読む スポンサード リンク
