一个函数声明function。function就是声明一个代码块,使用了function的都是全局函数,会优先执行,即你先使用后声明也行(被称为函数提升)。 为了方便使用,需要一些预定义的函数(称之为复杂类型)。Array(),Bollean(),Date(),Number(),String(),RegExp,Events。 object是所有复杂类型的父类型。复杂类型是esmascript中...
A parameter is an object. In addition to the parameters that each API itself needs to pass, the following common parameters are also required: success: The callback function that is executed when the API call succeeds. fail: The callback function that is executed when the API call fails. ...

A function call is marked as "pure" if a comment annotation /*@__PURE__*/ or /*#__PURE__*/ immediately precedes the call. For example: /*@__PURE__*/foo(); arguments (default: true)— replace arguments[index] with function parameter name whenever possible. arrows (default: true)...

To create a polyphonic synthesizer, use Tone.PolySynth, which accepts a monophonic synth as its first parameter and automatically handles the note allocation so you can pass in multiple notes. The API is similar to the monophonic synths, except triggerRelease must be given a note or array of ...

{functionmakeInteger(digits){returnparseInt(digits.join(""),10)}}interger=digits:[0-9]+{returnmakeInteger(digits);} 以上就是PegJS语法的基本使用方法,我们可以用它来定义各种复杂的解析规则。 现在我们开始尝试去解析一个简单的JCE文件吧,它主要由两部分组成:struct和interface。struct定义了数据类型,interface...
