Strategy Game Example

Here is an example of how the + and += operators might be used in the context of a strategy game:

let playerResources = 50;

function gatherResources(gathered) {
  playerResources += gathered;
  console.log(`You have gathered ${gathered} resources. Your total is now ${playerResources}.`);
}

gatherResources(20); // Outputs "You have gathered 20 resources. Your total is now 70."
gatherResources(30); // Outputs "You have gathered 30 resources. Your total is now 100."

let unitCost = 10;
let unitsToCreate = 3;

if (playerResources >= unitCost * unitsToCreate) {
  playerResources -= unitCost * unitsToCreate;
  console.log(`You have created ${unitsToCreate} units. Your resources are now ${playerResources}.`);
} else {
  console.log(`You do not have enough resources to create ${unitsToCreate} units.`);
}

In this example, we have a variable called playerResources that stores the number of resources that the player has. We have a function called gatherResources that adds a given amount of resources to the player's total.

We also have a few variables called unitCost and unitsToCreate that store the cost and number of units that the player wants to create. We use the + operator to add the gathered resources to the player's total, and we use the += operator to update the player's total after units are created.

Finally, we use an if statement to check if the player has enough resources to create the desired number of units. If they do, we use the * operator to calculate the total cost and the -= operator to subtract the cost from the player's resources. If they don't have enough resources, we display a message to the player
