Different memory allocation to both arrays... So different h [] [] These are also not equal.

Same means ye puch rhe ho ki same hai ya nahi They are not exactly same kyuki uski pehli value null hai First wale me a[0] karoge toh undefined milega Or usme null Shayd Check krlo

        Haa Lekin hum array ko empty rakhte hain. Agar append kroge data toh first value null ayegi Agar reassign kroge no problem
