It’s a the right shift assignment operator so x >>= 4 right shifts x by 4 and assigns the result back to x. The code editor is displaying single double wide symbol (ligature) instead of the three character long operator >>=, I discovered today these are in fact well loved by some coders.
What is that weird >>=== symbol? Looks like a cross breed between C and JavaScript here.
