4.2.1 Array literals: optionally block-like

Any array literal may optionally be formatted as if it were a “block-likeconstruct.” For example, the following are all valid (not an exhaustivelist):

someMethod(foo, [
  0, 1, 2,
], bar);

Other combinations are allowed, particularly when emphasizing semantic groupingsbetween elements, but should not be used only to reduce the vertical size oflarger arrays.

4.2.2 Object literals: optionally block-like

Any object literal may optionally be formatted as if it were a “block-likeconstruct.” The same examples apply as . Forexample, the following are all valid (not an exhaustive list):

const c = {a: 0, b: 1};
  a: 0, b: 1,
}, bar);

4.2.3 Class literals

Example:

foo.Bar = class extends Foo {
  /** @override */
  method() {
    return super.method() / 2;
  }
};
/** @interface */
class Frobnicator {
  frobnicate(message) {}

4.2.4 Function expressions

When declaring an anonymous function in the list of arguments for a functioncall, the body of the function is indented two spaces more than the precedingindentation depth.

Example:

4.2.5 Switch statements

After a switch label, a newline appears, and the indentation level is increased+2, exactly as if a block were being opened. An explicit block may be used ifrequired by lexical scoping. The following switch label returns to the previousindentation level, as if a block had been closed.

A blank line is optional between a break and the following case.

Example:

switch (animal) {
  case Animal.BANDERSNATCH:
    handleBandersnatch();
    break;
  case Animal.JABBERWOCK:
    handleJabberwock();
    break;
  default:
}
