if_return (default: true)— optimizations for if/return and if/continue imports (default: true)— drop unreferenced import symbols when used with unused inline (default: true)— inline calls to function with s
Return statement cannot appear outside the function. BadBreak1019 Cannot havebreakoutside the loop. BadContinue1020 Cannot havecontinueoutside the loop. BadHexDigit1023 Expected hexadecimal digit. NoWhile1024 Expectedwhile. BadLabel1025 There is already a label that has that name. ...
platform level, but what if you wish to test and generate pure Node chaos like check how your Node process copes with uncaught errors, unhandled promise rejection, v8 memory overloaded with the max allowed of 1.7GB or whether your UX remains satisfactory when the event loop gets blocked often...
if_return (default: true)— optimizations for if/return and if/continue imports (default: true)— drop unreferenced import symbols when used with unused inline (default: true)— inline calls to function with simple/return statement: false— same as 0 0— disabled inlining 1— inline simple ...
`bare_returns` Allow return outside of functions. Useful when minifying CommonJS modules and Userscripts that may be anonymous function wrapped (IIFE) by the .user.js engine `caller`. `spidermonkey` Assume input files are SpiderMonkey

"A 'continue' statement can only be used within an enclosing iteration statement.": "\"continue\" 语句只能在封闭迭代语句内使用。", "A 'break' statement can only be used within an enclosing iteration or switch statement.": "\"break\" 只能在封闭迭代或 switch 语句内使用。", ...
JSC Shell为JavaScript引擎提供了Repeat-Eval-Print-Loop(REPL)环境。此外,它还允许通过命令行传递JS脚本,该脚本由JSC Shell读取,由引擎解析和执行。 Shell的源代码可以在jsc.cpp中找到。 Shell的入口点是jscmain。这个函数负责初始化Web模板框架(WTF),该模板是Webkit代码库中的一组常用功能,并在创建JSC vm之前解析...
Node.js runs the V8 JavaScript engine, the core of Google Chrome, outside of the browser. Node.js is able to leverage the work of the engineers that made (and will continue to make) the Chrome JavaScript runtime blazing fast, and this allows Node.js to benefit from the huge performance...
The function expression unfortunately looks like the function statement. It may appear anywhere that an expression may appear, but not in statement position and not in a loop. It produces a function object but does not create a variable in which to store it.function (parameters) { statements...
