This TypeScript code is a simple program that stores a favorite number in a variable and then creates a message using that variable to reveal the favorite number. Finally, it prints the message to the console.

Here's a breakdown of the code:

1. let favoriteNumber: number = 7: This line declares a variable named favoriteNumber of type number and assigns it the value 7. In TypeScript, you can explicitly specify the data type of a variable using the colon (:) syntax.

2. let message: string = My favorite number is ${favoriteNumber};: This line declares another variable named message of type string. The value of the message variable is created using a template literal (backticks: `), which allows us to embed expressions inside the string using ${...}. In this case, the template literal includes the favoriteNumber variable using ${favoriteNumber}, resulting in the message being formed with the favorite number.

3. console.log(message): This line uses the console.log() function to print the message variable to the console. The message will be displayed as "My favorite number is 7" in this case, as the favoriteNumber variable was set to 7 earlier.

So, when you run this TypeScript code, it will print the message "My favorite number is 7" to the console. If you change the value of the favoriteNumber variable, the message will be updated accordingly when the program is executed.
