## Summary
- Update URLs in .editorconfig and .jshintrc files
- Add new rules to .eslintrc file for code style consistency
- Remove .jshintrc file
- Update node.js versions in .travis.yml file

## Details
The URLs in the `.editorconfig` and `.jshintrc` files were updated to use HTTPS instead of HTTP. In addition, the `.eslintrc` file was updated with new rules for code style consistency, including requiring `let` or `const` instead of `var`, enforcing spacing before blocks and functions, requiring parens in arrow function arguments, using template literals instead of string concatenation, and more.

The `.jshintrc` file was removed as it is no longer needed. Finally, the node.js versions in the `.travis.yml` file were updated to include newer versions.
