arcgis javascript how can i turn off layers

i am doing the tutorial for displaying the map in a web browser
https://developers.arcgis.com/javascript/3/jshelp/intro_agstemplate_amd.html
now I have the code, what if I don't want to display all the layers, and want to turn off the first layer?
i can do it by index of the layer, or can i use the layer name?
trying to understand i got to https://developers.arcgis.com/javascript/3/jsapi/arcgisdynamicmapservicelayer-amd.html but not sure how to use javascript
thanks guys.
If you want to turn off and on layers manually, I would use the layerlist widget script LayerList widget
or if you need the option to reorder the layers with the ability to turn layers on or off manually I would use the Reorder layers in map service

Adding new places in google maps

I am using Google javascript api Currently. I would like to add new places like add small villages in the map, these small village does not appear in google map even when I am highest zoom. I know villages Lat/Lang and would like to add them when someone zoom in map (placed in my website).

How do you create custom interactive areas on Google Maps?

I'm trying to create a map that shows county/district areas using Google Maps that will allow users to click on the area to retrieve relevant pop up information.
I have two datasets that I think would help, one being a list of UK Postcodes which would in turn allow me to determine different postal areas and the other is a dataset from Ordance Survey that contains province borders (county/district borders).
I've looked into KML Files and ImageMap but I'm not sure how to create these areas using the data I have?
I'm looking to achieve the sort of map that is used here:

Any help is greatly appreciated!
Thanks.
The way to work with Google maps is by using their api closely. You cannot go with simple image mapping.
Try those two links for starters:
https://developers.google.com/maps/documentation/javascript/examples/polygon-simple
and
https://developers.google.com/maps/documentation/javascript/reference#Polygon.
In short - you may need to draw a polygon for every area, bind a click event to it, then show Info Window with the relevant information for the user.
In case you're new to google maps, you may need to take more time inspecting their Api and the examples they give.
Best regards.

Customizing look of google map

I would change look and feel of Google map , is this possible .I would like to show only country co-ordinates.I want to show only countries with boundaries highlighted.If yes can you please let me know how this could be done.
This is possible, google maps has a full API that gives you loads of control over how your map looks.
https://developers.google.com/maps/documentation/javascript/
If you want to make life a little easier for yourself you can use this plugin.

image map question

I am searching for a script similar to mapper.js or Map Hilight which will allow me to control the colours of the map areas. I found found a few that work well but I also want to control the unactive state. This is where most fall flat. What I want to accomplish is on page load a map will appear and each map area will be a different shade of blue according to population density.
Please let me know if anyone knows of a good script I can use, cheers
UPDATED
Thanks guys, I managed to solve this using the map hilight script
what I did was actually really simple, just another case of RTFM or in this case, documentation. I used the Map Hilight script (http://davidlynch.org/js/maphilight/docs/).
In the js file there is an option: alwaysOn: true, I set this to false. Then I added this class to every area tag: class="{fillOpacity:'0.5'}"
I used the fill opacity to change the opcacity for each area based on the population density. Cheers
