Ruby If Then Else Inline

Note that else if is actually spelled elsif without the e.

Ruby if then else inline.

The built in if then else syntax is inline. If a b result x else result y end. If stock 1 puts sorry we are out of stock else puts thanks for your order end. Ternary shortened if statement syntax.

The if else statement. Executes code if the conditional is true. These can be rewritten as the following statement. Notice ruby uses elsif not else if nor elif.

Result if a b x else y end. Remember using unless in ruby is just the reverse of using if. If var 10 print variable is 10 elsif var 20 print variable is 20 else print variable is something else end. This could also be written as.

Num 10 if num 0 num 1 end puts num 11 when to use if. Has type bool a a a. Ruby provides a neat inline form for if else statements when the logic in your script is simple. You can also say if this is not true then do this other thing.

Ternary syntax is the same in ruby as most languages. A traditional if else construct in ruby is written. An if expression s conditional is separated from code by the reserved word then a newline or a semicolon. You re saying if this is not true then do this.

If the conditional is not true code specified in the else clause is executed.
