Why you should care

[/vc_column_text][vc_column_text]SWITCH statements are useful when there are many different cases depending on the value of the same expression. However, code will me more readable with IF statements for one or two cases.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]CAST Highlight counts one occurrence each time a SWITCH structure has less than 3 cases statements.

Bad Code

switch (variable) {
case 0:
doSomething();
break;
default:
doSomethingElse();
break;
}

Good Code

switch (variable) {
case 0:
doSomething();
break;
case 1 : 
doSomething();
break;
default:
doSomethingElse();
break;
}
