The use of operators pairs (``++=+++``, ``++=-++`` or ``++=!++``) where the reversed, single operator was meant (``+++=++``, ``++-=++`` or ``++!=++``) will compile and run, but not produce the expected results. This rule raises an issue when ``++=+++``, ``++=-++`` and ``++=!++`` are used without any space between the two operators and when there is at least one whitespace after. == Noncompliant Code Example ---- let target =-5; let num = 3; target =- num; // Noncompliant; target = -3. Is that really what's meant? target =+ num; // Noncompliant; target = 3 ---- == Compliant Solution ---- let target = -5; let num = 3; target = -num; // Compliant; intent to assign inverse value of num is clear target += num; ----
