What is \0 in a string?

Question

I am aware of string escapements which can be used to insert special characters, for example there is the \u---- escapement, where - is a hexadecimal digit, which can be used to insert any utf-16 character. I mean can be used to insert any character with its utf-16 code. Except emoji which take up two "characters" which arent really characters because the emojis are actually just utf-32 characters. Except the emojis which are a pictograph followed by U+FE0F. Anyways, what is the function of \0 in a string?

I have tried searching on google and stackoverflow and even w3school's javascript String lesson and could not find anything.

Answer 1

This is the escape sequence for the null character.
