customize js2-mode switch indentation

Question

This is pretty simple but it's thwarting me:

this is how a switch statement indents in js2-mode

  switch(letterGrade){
  case "A+":
    value = 100  ; break;
  case "A":
    value = 97 ; break;

this is how I want it to indent:

  switch(letterGrade){
    case "A+":
      value = 100  ; break;
    case "A":
      value = 97 ; break;

How can I make that happen? And, as a side question, why doesn't js2-mode use the same indenting stuff as other C-like languages?

Answer 1

js2-mode derives from js-mode. So you need set up js-mode in this case.

(setq js-switch-indent-offset 2) is enough.
