Explain Data Type’s in Java Script?
https://www.computersprofessor.com/2016/06/explain-data-types-in-java-script.html?m=0
Programming languages usually have
several different types of data commonly programmers may use characters,
integers, boolean, strings/ordered set of characters and reals (complex numbers).
Java script has only four types of
data
1) Numeric
2) String
3) Boolean
4) Null.
1) Numeric: These are basic numbers they can be
integers such as 56, 289, 5 (or) floating values like 88.91, 86.96….. you do
not need to differentiate between them.
2) Strings: These are
collection of character’s that are not numbers. The value of a string can
even contain spaces and may be totally made from digits.
Eg:
name = “chirs Bates”
name = ‘chirs Bates’.
name = “1234”
Nesting
strings one inside another is also possible. The best approach is to
use “ “ for the outer string and use ‘ ‘ for all inner strings.
Eg: “Chirs ‘Bates’ ”

3.Boolean: Boolean variables
hold the values ‘true’/false’. It is used in conditional test.
4.Null: Null value means
that one has not yet been decided. It doesn’t mean null (or) zero.
