Ruby If Then Else Inline

A traditional if else construct in ruby is written.

Ruby if then else inline.

Ternary shortened if statement syntax. An if expression s conditional is separated from code by the reserved word then a newline or a semicolon. Result if a b x else y end. The values false and nil are false and everything else are true.

The expression if predicate then expr1 else expr2. Num 10 if num 0 num 1 end puts num 11 when to use if. If the conditional is not true code specified in the else clause is executed. You re saying if this is not true then do this.

If a b result x else result y end. These can be rewritten as the following statement. 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.

The if else statement. If stock 1 puts sorry we are out of stock else puts thanks for your order end. This could also be written as. Note that else if is actually spelled elsif without the e.

If var 10 print variable is 10 elsif var 20 print variable is 20 else print variable is something else end. Notice ruby uses elsif not else if nor elif. Has type bool a a a. The built in if then else syntax is inline.

Executes code if the conditional is true.
