I am a newbie Angular developer. I am having a problem with the push method. It has the error ERROR Error: this.signupForm.get(...).push is not a function. I have made references to a lot of websites and other posts in Stackoverflow, but it doesn't work. Here is my code and I also comment which line contains the error in app.component.ts

You need to change the below line.
The form array only has the push method, you were using form control which caused the issue!
Before:
hobbies: new FormControl([]),
After:
hobbies: new FormArray([]), // <- changed here
