no-undef does not catch Promise

Update (from DelvarWorld):

Since this is the first google result for “eslint promise is not defined” I feel like it would be helpful to explicitly state the solution to this error here:

add "env": { "es6": true } to your .eslintrc.

The no-undef rule allows references to the global variable “Promise” even if it’s not marked as a global (which is problematic because IE does not have a global Promise.)

Here’s a test case, which can be added to the invalid section of no-undef.js.

        { code: "new Promise();", errors: [{ message: "\"Promise\" is not defined.", type: "Identifier"}] },

If the bug is accepted I’m happy to create a patch.

ESList version: 1.6.0 (ca3cc886f0eb65088c4cbe0585a74427f93422aa)

Alternatively, define the global in .eslintrc:

{
  "globals": {"Promise": true}
}
