SyntaxError: Invalid regular expression on line 392 about data-store

[jonschlinkert]

Changed it to:

A negative lookahead won't work. The node version is wrong in package.json, it should be 8.6 I think.

And it hasn't errored yet. I don't know if my fix will break anything though.

Are you saying all of the unit tests passed?

@jonschlinkert haven't run unit tests, but it worked to temporarily fix my project.

Before change:

store
    create
      ✓ should create an instance of Store
      1) should create a store with the given `name`
      ✓ should initialize a store with the given defaults
    set
      2) should `.set()` a value
      ✓ should `.set()` an object
      3) should `.set()` a nested value
      4) should save data that is added directly to `storedata`
    union
      5) should add and arrayify a new value
      6) should uniquify duplicate values
      7) should union an existing value
    has
      8) should return true if a key has a value
      9) should return true if a nested key has a value
    hasOwn
      10) should return true if a key exists
      11) should work with escaped keys
      12) should return true if a nested key exists
    get
      13) should `.get()` a stored value
      14) should `.get()` a nested value
    union
      15) should `.del()` a stored value
    del
      16) should delete stored values
      17) should delete a nested stored value
      18) should ignore nested properties that do not exist
      19) should delete multiple stored values
    json
      20) should use the indent value defined on ctor options

  20 failing

...all the fails are because

  1) store hasOwn should work with escaped keys:

I eliminated the regex negative lookbehind that caused the error. Thanks for creating the issue
