Variables, Datatypes and Operators in JavaScript.

Datatypes in JavaScript:

Data of these types are stored and manipulate easily by using variables.

How to creates variables:

Numbers:

String:

Boolean:

Objects:

When we don’t assign any value to variable, It will give you undefined.

If we don’t want to store any data in our variable then we can assign a variable with an empty value called as ‘null’.

Operators:

• Operators are categorized into unary, binary, and ternary based on the number of operands on which they operate in an expression.

• “typeof” is an operator in javaScript.

Example of typeOf:

Equality Operator:

Concatenation Operator:

console.log("string: ","Hello" + " world!");  // string: Hello world!

Exponentiation Operator:

console.log("10**3", 10**3); // output 1000
