Well the “ha” (は) pronounced “wa” is basically like a pointer to the word before it. Like smb. comments “THIS” after it.
The “wa” (わ) character on the other hand is used as a letter in a word. It won’t usually stand alone in a sentence (which is a bit weird since the japanese usually don’t use spaces so you just have to guess/know)
The は is also used in words so have fun knowing when it is a particle and when not.
I am just a beginner on japanese.
Yeah, don’t confuse people if you don’t know anything about a language.
That’s like saying ‘I was so confused what an atre is, until I realized it’s not the atre but theatre!’
は and が are something you can call ‘subject markers’, just like を is an object marker. They come after words to describe their position in a sentence. The same way you have Kasus/Fälle in German.
