Let a = [ ] vs. Let a = [ null ] both are same or not????

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

Kese

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

To null hum kb dete h jb value pta nhi ho ..right And after performing some function then null ki jgh values aayegi na!!🙄 -------------------------------- To empty array me bhi to value hme pta nhi h..to after performing some function then comes values naa🤔

Wait Mujhe samjh ni aa rha after performing some function kya hota hai Wait

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

Here is it..

What is Null array in javascript ? I don't know

0th index pr🤔

Ha

Btaya maine Pehle Wale me undefined ayega Second me null aana chahiye

Ok mean it
