Javascript if else loop?

I'm sure there probably is, however I'm not sure what it's called so apologises if this is something super similar. I'm wondering if there's a faster way to code the following:

var b = "#ff0002";
var o = "#46c029";
var i = "#f2ec00";
var n = "#f64c98";
var g = "#52c6f3";

if(a==1){
    return b;
}else if(a==2){
    return o;
}else if(a==3){
    return i;
}else if(a==4){
    return n;
}else if(a==5){
    return g;
}
