What is the purpose of this pull request? (put an "X" next to item)

[x] Bug fix

Tell us about your environment

  • ESLint Version: master
  • Node Version: 7.7.4
  • npm Version: 4.1.2

What parser (default, Babel-ESLint, etc.) are you using?

default

Please show your full configuration:

rules:
  dot-notation: error

What did you do? Please include the actual source code causing the issue.

1['toString']

What did you expect to happen?

I expected the autofixer to produce valid syntax:

1 .toString

What actually happened? Please include the actual, raw output from ESLint.

The autofixer produced invalid syntax:

1.toString

What changes did you make? (Give an overview)

Previously, when fixing a computed property access from a number literal, the dot-notation autofixer would place a dot immediately after the number literal. However, a dot after a decimal integer literal gets parsed as a decimal point, not a property accessor. This commit updates the fixer to insert a space before the dot when the object is a decimal integer literal.

Is there anything you'd like reviewers to focus on?

Nothing in particular
