Always modify arrays by using an Array instance method, or replacing it entirely. Vue provides a convenience method `arr.$set(index, value)` which is syntax sugar for `arr.splice(index, 1, value)`.

 All Vue.js templates are valid, parsable HTML markup, and Vue.js relies on spec-compliant parsers to process its templates. However, as specified in the standard, HTML is case-insensitive when matching tag and attribute names. This means camelCase attributes like `:myProp="123"` will be matched as `:myprop="123"`. As a rule of thumb, you should use camelCase in JavaScript and kebab-case in templates. For example a prop defined in JavaScript as `myProp` should be bound in templates as `:my-prop`.

 Second, because `templateURL` loads the template via Ajax at runtime, you don't need a build step in order to split up your files. This is convenient during development, but comes at a serious cost when you want to deploy it to production. Before HTTP/2 is universally supported, the number of HTTP requests is still probably the most critical factor in your app's initial load performance. Now imagine you use `templateURL` for every component in your app - the browser needs to perform dozens of HTTP requests before even being able to display anything! In case you don't know, most browsers limit the number of parallel requests it can perform to a single server. When you exceed that limit, your app's initial rendering will suffer for every extra round trip the browser has to wait for. Sure, there are build tools that can help you pre-register all those templates in `$templateCache` - but that shows us a build step is, in fact, inevitable for any serious frontend development.
 
-So, without `templateURL`, how do we deal with the development experience problem? Writing templates as inline JavaScript strings is terrible, faking templates with `<script type="x/template">` also feels like a hack. Well, maybe it's time to up the game a bit and use a proper module bundler like [Webpack](http://webpack.github.io/) or [Browserify](http://browserify.org/). It might seem daunting if you've never dealt with them before, but trust me it's worth it to take the leap. Proper modularization is a necessity if you want to build anything large and maintainable. More importantly, you get to write your [Vue components in a single file](http://vuejs.org/guide/single-file-components.html), with proper syntax highlighting and the extra benefits of custom pre-processors, hot-reloading, ES2015 by default, autoprefixing and scoped CSS, which makes the development experience 10 times better.

 That's it. With all those bits and pieces created we can now re-use the `GoogleMapLoader` component as a base for all our maps by passing different templates to each one of them. Imagine that you need to create another map with different Markers or just Markers without Polylines.
