Switch / Case / Default

A switch statement checks the source and compares it against several declared patterns. It then executes the first case pattern that resolves to true. or a default one if nothing resolves to true (and default is provided).A switch statement is equivalent to chaining multiple if statements one after another.

Syntax

Basic syntax of switch tag is as follows:

                                                        
                                                        
                                                            {[ switch [statement] ]}
                                                           {[ case 1 ]}
                                                           Executes when statement equals 1
                                                        {[/]}
                                                        
                                                            

You can chain as many cases one after another:

                                                        
                                                        
                                                            {[ switch [statement] ]}
                                                           {[ case 1 ]}
                                                           Executes when statement equals 1
                                                           {[ case 2 ]}
                                                           Executes when statement equals 2
                                                           {[ case 3 ]}
                                                           Executes when statement equals 3
                                                        {[/]}
                                                        
                                                            

Additionally, compared to strongly typed languages, you can check against multiple data types at the same time:

                                                        
                                                        
                                                            {[ switch [statement] ]}
                                                           {[ case 1 ]}
                                                           Executes when statement equals 1
                                                           {[ case true ]}
                                                           Executes when statement equals 2
                                                           {[ case "Some text" ]}
                                                           Executes when statement equals 3
                                                        {[/]}
                                                        
                                                            

Default fallback

Additionally, you can use default case to fallback to it when all other cases fail. Default case is optional:

                                                        
                                                        
                                                            {[ switch [statement] ]}
                                                           {[ case 1 ]}
                                                           Executes when statement equals 1
                                                           {[ case 2 ]}
                                                           Executes when statement equals 2
                                                           {[ default ]}
                                                           Executes when statement equals to anything other than 1 or 2
