Chronology of learning spring and in particular boot and rest. What is Spring Boot used for?

Question

Java

At the moment I'm studying Spring, I've already mastered IOC, MVC, Data JPA, Security, but I just can't understand what Spring Boot is used for, and is it even worth learning? Prompt video tutorials or articles (can be paid) on the topic of Spring boot and Spring rest. And also explain in a nutshell why Boot is needed and what is its difference from MVC?
Thanks in advance.

Answer 1

Boot is just an autoconfigurator and a launcher that allows you not to manually write the context configuration and deploy the application on the application server.

SB is mainly useful for quickly generating projects via Spring Initializr https://start.spring.io/ and to docker
