What is the role of the triple equals operator in comparing values in a programming language?

In JavaScript (and Node.js), the triple equals operator === is used for strict comparison of two values. Unlike the double equals ==, which performs type coercion before comparison, === compares both value and type without coercion.

For example:

1 == '1'    // true, because '1' is coerced to number 1
1 === '1'   // false, different types (number and string)

true == 1   // true
true === 1  // false

Using === is recommended to prevent unexpected results due to implicit type conversion.
