• 1 You can drop the == true since they both return booleans. – cs95 Commented Jul 4, 2017 at 19:23
• 2 If this condition if (function1() && function2() ){ is true, it means that these functions was executed and returned true. – davidxxx Commented Jul 4, 2017 at 19:24
• just be aware of that if the first function doesn't return true or the second won't be executed. – NtFreX Commented Jul 4, 2017 at 19:24
• Should function2() be called regardless of function1()'s return value or only when it returns true? – Marvin Commented Jul 4, 2017 at 19:24

As a side note, your code can be shorten to

if (function1() && function2()){
