Explaining the result of an arithmetic expression in JavaScript
+1
−5
I misunderstand why the following code outputs -1 in console.
x = 42;
x = (x == 42) * -1 + (x != 42) * x;
-1
Due to Type Coercion, the comparison of x to 42 yields true and is thus translated to 1.
So 1 * -1 yields -1.
Now, (x != 42) which is false yields 0 so I have expected to get in console
-42
Because -1 + 0 * 42 MEANS -42.
So why did I get -1 in the end?
