Question

how can i convert this nested if statement to something more readable and ‘elegant’?

if(speed==0){
            othvalue=0;
        }else {
            if(speed>value1864cmn){
                othvalue=value1864cmn;
            }else {
                if(speed>value1746cmn){
                    othvalue=value1746cmn;
                }else {
                    if(speed>value1628cmn){
                        othvalue=value1628cmn;
                    }else {
                        if(speed>value1510cmn){
                            othvalue=value1510cmn;
                        }else {
                            if(speed>value1392cmn){
                                othvalue=value1392cmn;
                            }else {
                                if(speed>value1274cmn){
                                    othvalue=value1274cmn;
                                }else {
                                    if(speed>value1156cmn){
                                        othvalue=value1156cmn;
                                    }else {
                                        if(speed>value1038cmn){
                                            othvalue=value1038cmn;
                                        }else {
                                            if(speed>value920cmn){
                                                othvalue=value920cmn;
                                            }
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
            }
        };

You can use “match” construct:

var othvalue = (speed == 0) ? 0 
             : (speed <= 10) ? 10
             : (speed <= 20) ? 20
             : (speed <= 30) ? 30
             : 40;
