众所周知，PHP 是最好的语言。
而 JS 则是最魔幻的语言，持续记录使用中的魔幻时刻：
- 学了一半的
in
!(1 in {1: 1}) // false
1 not in {1: 1} # false
- 不
break就会“漏”的switch
const foo = 0;
switch (foo) {
case -1:
console.log("negative 1");
break;
case 0: // Value of foo matches this criteria; execution starts from here
console.log(0);
// Forgotten break! Execution falls through
case 1: // no break statement in 'case 0:' so this case will run as well
console.log(1);
break; // Break encountered; will not continue into 'case 2:'
case 2:
console.log(2);
break;
default:
console.log("default");
}
// Logs 0 and 1
foo = 0
match foo:
case -1:
print("negative 1")
case 0:
print(0)
case 1:
print(1)
case 2:
print(2)
case _:
print("default")
