# Difference Between == and === in Javascript

### Let's first understand What is == and === in Javascript

The '==' and '===' operators are used to compare if two values are equal

Some Examples of using '==' and '===' operators

## Difference between '==' and '==='

1. The '==' operator is called **loose equality operator**
    

* it compares two values and also does type conversion
    
* When comparing two variables the "==" operator tends to transfer data from one type to another.

1. The '===' operator is called **Strict equality operator**
    

* it will strictly compare the values of both variables and only if they are exactly equal it will return true otherwise it will return false.
    
* the condition for this operator it checks whether both the value and type are equal.

**Example of using '==' and '===' with objects**

* while comparing the objects with '==' and '===' operands it will result in false condition because the reference of the object is different but the properties are same.
    

# conclusion-

* '' == '' will check the type and if they are not the same it will perform a type conversion and then show the result
    
* " === " will check the type, if that matches then will check the value and show the result. if the type is not the same it will result as false.
