Different between == and === in javascript
The == operator checks for equality of values after converting the operands to the same type. This process is called type coercion. For example, 1 == '1' would return true because JavaScript coerces the string '1' to the number 1 before comparison.
On the other hand, the === operator, known as the strict equality operator, not only checks for equality of values but also ensures that the operands are of the same type. It does not perform type coercion. So, 1 === '1' would return false because they are of different types.
In essence, == is more lenient as it allows type coercion, while === is strict and requires both value and type to be the same for equality.
