javascript: throw new error without displaying to user -

is there way can use throw new error in javascript , hide display or change display of console window? throwing error end program.

put program's execution within try/catch. can handle error want to. however, seems pretty hack-ish way terminate execution.

function run_my_program(){    //do here    throw "i want break world!"; } try{    run_my_program(); } catch(err) {     //do whatever want err }
