Equality Testing

In JavaScript, the == (double equals) and === (triple equals) are comparison operators used for equality testing.

Double Equals (==)

• Performs type coercion before making the comparison.
• If the operands have different types, JavaScript tries to convert them to a common type before making the comparison.
• For example, "5" == 5 will be true because the string "5" is coerced into the number 5 for the comparison.

Triple Equals (===)

• Does not perform type coercion; it checks both value and type for equality.
• If the operands have different types, the comparison evaluates to false.
• For example, "5" === 5 will be false because the string and number are of different types.
