Update Initializers to class factory syntax IV

[sashadev-sky]

First Time?

This is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before, or even folks who haven't contributed to open source before.

If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from groups underrepresented in free and open source software!

We know that the process of creating a pull request is the biggest barrier for new contributors. This issue is for you 💝

If you have contributed before, consider leaving this one for someone new, and looking through our general help wanted issues. Thanks!

🤔 What you will need to know.

Nothing. This issue is meant to welcome you to Open Source :) We are happy to walk you through the process.

The problem

What's supposed to happen:

From the official Leaflet docs:

Class Factories
You may have noticed that Leaflet objects are created without using the new keyword. This is achieved by complementing each class with a lowercase factory method:

new L.Map('map'); // becomes:
L.map('map');

What actually does happen:

We use built-in Leaflet classes such as L.LatLngBounds', L.LatLng, and L.Map`, but we don't take advantage of their suggested class factory syntax. Let's clean up the below file a bit to do that:

Solution

1. remove all 3 new keywords from this line, change the initializer to L.latLngBounds, and change the other initializers to L.latLng
   

   mapknitter/app/views/maps/index.html.erb

   Line 126 in 204dd5e

   var bounds = new L.LatLngBounds(new L.LatLng(84.67351257 , -172.96875) , new L.LatLng(-54.36775852 , 178.59375)) ;

2. This one is 1/2 way done. All we need to do here is remove the new keyword
   

   mapknitter/app/views/maps/index.html.erb

   Lines 127 to 130 in 204dd5e

   	var Mapknitterunique = new L.map('mapknitter-unique' , {
   	maxBounds: bounds ,
   	maxBoundsViscosity: 0.75
   	}).setView([43, -83] , 2);

Thanks!!

Hi, @sashadev-sky

I would like to work on this, please.

Is the solution section all I need to do? If so, I'm kind surprised XD
