What are the loops in JavaScript?
JavaScript supports different kinds of loops:
- for – loops through a block of code a number of times.
- for/in – loops through the properties of an object.
- for/of – loops through the values of an iterable object.
- while – loops through a block of code while a specified condition is true.
What are the three data types in JavaScript?
JavaScript allows you to work with three primitive data types: numbers, strings of text (known as “strings”), and boolean truth values (known as “booleans”). JavaScript also defines two trivial data types, null and undefined, each of which defines only a single value.
How many Basic types of loops are there?

What is data type in Javascript?
Data types describe the different types or kinds of data that we’re gonna be working with and storing in variables. In Javascript, there are five basic, or primitive, types of data. The five most basic types of data are strings, numbers, booleans, undefined, and null. We refer to these as primitive data types.
