Ruby if or condition.
A common perl idiom is.
Notice ruby uses elsif not else if nor elif.
These if experssions essentially check whether a condition is true or not.
You just need to understand their special place in ruby programs.
Executes code if the conditional is true.
Ruby conditional statements conditional statements are also known by the name of conditional processing or conditional expressions.
The stock 1 part is what we call a condition.
A b is true.
They are used to perform a certain set of instructions if a specified condition is met.

If var 10 print variable is 10 end.
Ruby if else statement tests the condition.
Checks if the value of left operand is greater than the value of right operand if yes then condition becomes true.
The ruby language has a very simple control structure that is easy to read and follow.
The conditions are generally of boolean type and return either true or false as the result.
In perl they were largely used to modify control flow similar to the if and unless statement modifiers.
This is what needs to be true for the code inside the condition to work.
And and or originate like so much of ruby in perl.
The values false and nil are false and everything else are true.
Stock 10 if stock 1 puts sorry we are out of stock end notice the syntax.
Here s the key difference between ruby and most other languages.
A b is not true.
If something is true the condition then you can do something.
