V7015. Suspicious formatting of assignment and unary operators.
The analyzer has detected suspicious formatting of the assignment operator and one of the unary operators: !, -, or +. It is most likely a mistake to use these operators—developers probably meant to use one of the following instead: !=, -=, or +=.
The analyzer flags the use of the assignment operator together with logical negation in the condition as suspicious:
let a = .... ;
let b = .... ;
....
if (a =! b) { // <=
....
}Most likely, the code should include a check that the a variable is not equal to b. If so, the correct code should look like this:
if (a != b) {
....
}If the goal is to perform an assignment rather than a comparison, it is preferable to fix the formatting to enhance the code's readability:
if (a = !b)
....A similar error can involve the + and - unary operators. For them, normal statements are considered suspicious, not conditions. Suspicious code may look like this:
let size = ....;
let delta ....;
....
size =- delta; // <=The code may be correct, but it likely contains a typo, and the developers probably intended to use the -= operator:
size -= delta;Was this page helpful?
