How can a compiler be written in the language it compiles?
You first write a compiler for your language (or a subset thereof) in some other language.

You use the former compiler to compile the new compiler, and then the new compiler can compile itself.
How does bootstrapping help in compilation?

What is cross compiler and bootstrapping?
7. A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. For example, a compiler that runs on a windows but generates code that runs on Android is a cross compiler. bootstrapping is the process of writing a compiler in the source prog.
