Ruby If Then Else Inline

These can be rewritten as the following statement.

Ruby if then else inline.

The if else statement. If the conditional is not true code specified in the else clause is executed. If stock 1 puts sorry we are out of stock else puts thanks for your order end. Num 10 num 1 if num 0 puts num 11.

Has type bool a a a. This could also be written as. Num 10 if num 0 num 1 end puts num 11 when to use if. Ruby provides a neat inline form for if else statements when the logic in your script is simple.

Ternary syntax is the same in ruby as most languages. An if expression s conditional is separated from code by the reserved word then a newline or a semicolon. The built in if then else syntax is inline. Result if a b x else y end.

If a b result x else result y end. A traditional if else construct in ruby is written. Note that else if is actually spelled elsif without the e. You re saying if this is not true then do this.

Executes code if the conditional is true. The values false and nil are false and everything else are true. Remember using unless in ruby is just the reverse of using if. You can also say if this is not true then do this other thing.

If var 10 print variable is 10 elsif var 20 print variable is 20 else print variable is something else end.
