Explain execution flow of following complex javascript return statement -

-

i've found hard follow execution flow of return statement. if explain how execution flows work , better if can explain whats pros , cons of creating such complex statements rather more readable multi-line statement appretiate.

return option = option ? option : {}, typeof option.xvalue == "boolean" && (_ready = option.xvalue), option.name && _ready == !1 && log(option.name + "(" + option.caller + " )  api not ready.", "e"), _ready

the expression uses comma operator multiple statements, , short-circuit operation of && operator if expression.

you can write code as:

if (!option) {   option = {}; } if (typeof option.xvalue == "boolean") {   _ready = option.xvalue; } if (option.name && _ready == false) {   log(option.name + "(" + option.caller + " )  api not ready.", "e") } return _ready;

the advantage of writing single complex expression is single complex expression. reason wanting might make code harder read, or perhaps shorter.
