jquery - Group mapping in JavaScript -

can make kind of mapping in javascript?

right can do

if (number < 32) {   group = 1; else if (number < 72) {   group = 2; } else if (number < 100) {   group = 3; } else {   group = -1; } 

instead of doing this, want inline mapping. put in function, wonder if javascript has smart way this, having group divisions defined in array or something.

you can use switch make little more readable, if want inline:

var group = number < 32 ? 1 : number < 72 ? 2 : number < 100 ? 3 : -1;
