JavaScript Data Types

Data types are a particular type of data item that determines what operations can be applied to them. Once a variable is assigned a data type it can be used for computations in the program. There are different types of data that we can use in a JavaScript program. For example,

 const x = 5;
 const y = "Hello";

Here,

• 5 is an integer data.
• "Hello" is a string data.
