javascript保留关键字

在javascript中，一些标识符是保留关键字，不能用作变量名或函数名

abstract arguments boolean break byte
case catch char class* const
continue debugger default delete do
double else enum* eval export*
extends* false final finally float
for function goto if implements
import* in instanceof int interface
let long native new null
package private protected public return
short static super* switch synchronized
this throw throws transient true
try typeof var void volatile
while with yield

javascript内置对象、属性和方法

Array Date eval function hasOwnProperty
Infinity isFinite isNaN isPrototypeOf length
Math NaN name Number Object
prototype String toString undefined valueOf

java保留关键字

getClass java JavaArray javaClass JavaObject JavaPackage

windows保留关键字

由于javascript可以在html外部使用，那么应该避免使用windows对象和属性的名称作为变量名及函数名
