有哪些东西是假值？
共6个：
0或+0、-0，NaN
""
false
undefined
null
上面的顺序是按照基本类型来排列的。
除此之外的一律不是！！哪怕是如下形式：
Infinity
'0'、'false'、" "（空格字符）
任何引用类型:[],{},function(){}
if (a && b)的正确理解方式是：a && b进行表达式求值后，然后再转换为Boolean类型。
&&是种短路语法，求值后不一定是个Boolean类型，更不是两边转化布尔值再运算。
比如 2&&3 的结果是3，不是true。
引用类型转换为布尔，始终为true
引用类型转换为字符串
1.优先调用toString方法（如果有），看其返回结果是否是原始类型，如果是，转化为字符串，返回。
2.否则，调用valueOf方法（如果有），看其返回结果是否是原始类型，如果是，转化为字符串，返回。
3.其他报错。
引用类型转化为数字
1.优先调用valueOf方法（如果有），看其返回结果是否是基本类型，如果是，转化为数字，返回。
2.否则，调用toString方法（如果有），看其返回结果是否是基本类型，如果是，转化为数字，返回。
3.其他报错。###js语言中最常用的单词
