Ruby ternary if null

Swift takes a cue from C and also has?? From PHP5 and on, you can leave out the middle part of a ternary operator to create a binary one. Apparently future versions of PHP might have a true?? Look at it like an emoji. In hindsight - after having a lot more experience with Ruby logic and logical operators in general - it makes perfect sense. The mix of various operators and assignment is simply referred to as abbreviated assignment.

Why have you put brackets around true? If multi-line, why not just use if Because of too many years working in Perl and C? I use either, depending on the situation and whether one is visually clearer than the other.

WayneConrad The if has at least one problem explained in this answer: stackoverflow. Because true is actually sitting in for what would be an expression that evaluates to true or false. It's better to visually delimit those since ternary statements can quickly devolve into visual noise, reducing readability which affects maintainability. AaronBlenkush Thanks for the elegant input. I am still in noob level, probably it is why : — devwanderer.

Combined comparison operator. Returns 0 if first operand equals second, 1 if first operand is greater than the second and -1 if first operand is less than the second. Add AND assignment operator, adds right operand to the left operand and assign the result to left operand.

Subtract AND assignment operator, subtracts right operand from the left operand and assign the result to left operand. Multiply AND assignment operator, multiplies right operand with the left operand and assign the result to left operand. Divide AND assignment operator, divides left operand with the right operand and assign the result to left operand. Modulus AND assignment operator, takes modulus using two operands and assign the result to left operand.

Exponent AND assignment operator, performs exponential power calculation on operators and assign value to the left operand. Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. Called Logical OR Operator.
