  • javascript保留关键字

    1.通用保留关键字

    break delete function return typeof
    case do if switch var
    catch else in this void
    continue false instanceof throw while
    debugger finally new true with
    default for null try  

    2.ECMAScript 5 增加保留

    class const enum export extends
    import super      

                

    3.普通下合法,但严格模式下是保留的

    implements let private public yield
    interface package protected static  

                    

    4.严格模式下做了严格限制,并不完全是保留字,但不能用作变量名,函数名或参数名

    arguments eval                               

      

    5.ECMAScript3关键字

    abstract double goto native static
    boolean enum implements package super
    byte export import private synchronized
    char extends int protected throws
    class final interface public transient
    const float long short volatile

                                                              

    6.Javascript预定义了很多全局变量和函数,应当避免把它们的名字用做变量名和函数名:

    arguments encodeURI Infinity Number RegExp
    Array encodeURIComponent isFinite Object String
    Boolean Error isNaN parseFloat SyntaxError
    Date eval JSON parseInt TypeError
    decodeURI EvalError Math RangeError undefined
    decodeURIComponent Function NaN ReferenceError URIError
