Why you should care

[/vc_column_text][vc_column_text]Having an unconditional break, return or throw in a loop renders it useless; the loop will only execute once and the loop structure itself is simply wasted keystrokes. Having an unconditional continue in a loop is itself wasted keystrokes. For these reasons, unconditional jump statements should never be used except for the final return in a function or method.[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_single_image image=”5362″ img_size=”full”][vc_row_inner][vc_column_inner][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]This Code Insight counts one occurrence each time one of these patterns is found into the source code:

return, break, continue is unconditional inside a loop.
return, throw is unconditional inside a method, unless it is the last instruction
break is unconditional in a case statement, unless it is the last instruction.
