This rule is deprecated, and will eventually be removed.

Why is this an issue?

Parentheses can disambiguate the order of operations in complex expressions and make the code easier to understand.

a = (b * c) + (d * e); // Compliant: the intent is clear.

Redundant parentheses are parenthesis that do not change the behavior of the code, and do not clarify the intent. They can mislead and complexify the code. They should be removed.

Noncompliant code example

let x = ((y / 2 + 1));  // Noncompliant

if (a && ((x + y > 0))) {  // Noncompliant
  return ((x + 1));  // Noncompliant
}

Compliant solution

let x = (y / 2 + 1);

if (a && (x + y > 0)) {
  return (x + 1);
}
