Golang

What is the dynamic variable assignment operator?

Write a line of code that creates a new router using the gorilla/mux library and assign it to variable router.

What function loads the environment variables from a .env file into the program's current environment? Hint: godotenv

Once we have loaded the .env into our program's environment, how would we assign the environment variable CLOUD_TOKEN to variable cloudToken? Use a dynamic assignment operator.

Given that we've initialized a router router, how would we start our server and begin listening to requests on port 2020? Hint: Look at the demo.

Now we're going to build a car in Golang. It has a color, numberOfSeats, numberOfWheels, and it may or may not have autopilot. Fill in the blanks to declare an object structure. Make sure to use UpperCamelCase when appropriate.

<a> Car <b> {
  <c> string `json:"color"`
  <d> <e> `json:"numberOfSeats"`
  <f> <g> `json:"numberOfWheels"`
  HasAutopilot <h> `json:"hasAutopilot"`
}

Fill in the blanks for <a>, <b>, <c>, <d>, <e>, <f>, <g>, and <h>.

Now that we've declared our Car, we're going to create an instance of it that we can use. Fill in the blanks for declaring a red Car car that has 5 seats, 4 wheels, and does not have autopilot. Hint: https://tour.golang.org/moretypes/2.

car := <a>{"red", <b>, 4, false}

Fill in the blanks for <a> and <b>.
