Equivalence of JS's increment/decrement operator and assignment operator with operation_javascript tips

1. Increment/decrement operator equivalence

a=b; a=b;b=b 1;
a= b ; b=b 1;b=b;
a=b--; a=b;b=b-1;
a=--b; b=b-1;b=b;

So, a=5;b=6;var3=a *--b, the result is 25

2. Assignment operator equivalent with operation

a*=b; a=a*b ;
a/=b; a=a/b;
a =b; a=a b;
a-= b; a=a-b;
a%=b; a=a%b;
a&=b; a=a&b; //Starting from &=, the following are bitwise operators
a|=b; a=a|b;
a^ =b; a=a^b;
a>>=b; a=a>>b;
a a=aa>>>=b; a=a>>b; //C# does not have this operation Talisman
