I need explanation on this array.

[EddiePumpin]

contract SimpleStorage {
uint256 public favouriteNumber;
People public person = People({favouriteNumber: 2, name: "Eddie"});

struct People { // A list of variable inside an object in solidity they get indexed automatically.
uint256 favouriteNumber;
string name;

People[] public people;

function addPerson(string memory _name, uint256 _favouriteNumber) public {
     People memory newPerson = People({favouriteNumber: _favouriteNumber, name: _name });
    people.push(newPerson);

Lets Explain it down..
Now the struct People contains the uint256 favouriteNumber; string name; . So now People becomes user defined data type so we can store our favoriteNumber & name.

And then you have allocating a memory space in name of People , In that you can store both favoriteNumber & name . And this Function passes two parameters 1st is _name that stores to the uint256 _favouriteNumber & 2nd parameter is stores in string memory _name.

And finally we push the newPerson (newly stored ones) into the array of People[] public people;.
Now if you call 0 index position, the passed arguments in that function that displays.
