Ruby Return Value Of Assignment

Once the is assigned a value the conditional assignment operator cannot be over written.

Ruby return value of assignment.

False return value statements to shorten your if else structures. Hashes enumerate their values in the order that the corresponding keys were inserted. When return isn t explicitly called within a method then ruby returns the value of the last executed instruction in the method in the implicit return method as if true is always evaluated as true. Result test 5 10 display the result.

Here is the syntax. That about covers methods. You are getting wiser and more confident with ruby. A literal ruby hash is created by placing a list of key value pairs between braces with either a comma or the sequence between the key and the value.

A trailing comma is ignored. For more detail on ruby arrays go through ruby arrays. Also called associative arrays they are similar to arrays but where an array uses integers as its index a hash allows you to use any object type. I see from the example that the conditional assignment operator can change an empty variable in ruby to a specific value say if a method where expressed within a block code.

Ruby program that uses implicit return value def test x y this expression is evaluated and returned. A hash is a dictionary like collection of unique keys and their values. It first evaluates an expression for a true or false value and then execute one of the two given statements depending upon the result of the evaluation. Since in our example number is assigned 3 this expression returns the number 5 and that is why the value returned by our method also is 5.

Ternary operator logic uses condition. The value of just assignment 2 is going to be 5 because the assignment expression evaluates to 5 therefore that s what s returned. X 10 y end call test with two arguments. True return value.
