Output in L-5 using metamask for deployment

Below is the code

const currentFavoriteNumber = await contract.retrieve();
    console.log(`Current favNUM=${currentFavoriteNumber.toString()}`);

    const transactonResponse = await contract.store("7");
    //const transactonReceipt = await transactonResponse.wait(1);

    const newCurrentFavoriteNumber = await contract.retrieve();
    console.log(`New favNUM=${newCurrentFavoriteNumber.toString()}`);

Why is it that if we do not write the following line we get output in terminal as -
Current favNum=0
New favNum=0

    const transactonReceipt = await transactonResponse.wait(1);

@Atharv-02 Write transaction takes time to update the state of the blockchain due to this we need to wait for the transaction to complete it is like the async calls in JavaScript. Without waiting for the transaction program will go further the read the blockchain state that obviously will not be updated which is why you are seeing both values same.
