Equivalent expression of the increment/decrease operator of JS and the value assignment operator with operations _ javascript technique

Equivalent formula of the increment/decrease operator of JS and the value assignment operator with operations 1. increment/decrease operator equivalent

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;

Therefore, a = 5; B = 6; var3 = a ++ * -- B, and the result is 25.

2. equivalent operator 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 operators are all bitwise operators
A | = B; <=>A = a | B;
A ^ = B; <=>A = a ^ B;
A> = B; <=>A = a> B;
A <= B; <=>A = a <
A >>> = B; <=>A = a> B; // C # This operator is not available
