Is bol === !0
exactly the same as bol == true
?
<>>Example:
function myFunction(bol){
if(bol===!0){
return 1;
}else{
return -1;
}
}
alert(myFunction(true));//1
如果我决定加以利用,我是否会遇到问题? (不同于法典的可读性)

<代码>1 = 真实 :true
,但1 == !0
为假。
由于!0
是true
,这相当于bol=真实
。 请注意,你应如何利用三个平等标志来确切地了解同样的行为。
<代码>=系指 Java将not<>m>在比较时试图胁迫这些数值。 如果你真的要胁迫want,你将使用=
。 然而,在这种情况下,<代码>if将只是强迫你:
if (bol) { ... }
基本不变
if (bol == true) { ... }
