Why is my string validation failing in JavaScript?

Correcting Incorrect Equality Comparison in Code

In your code, you aim to validate a string based on its length. However, your issue stems from an incorrect use of the assignment operator = instead of the equality comparison operator ==.

In JavaScript, = is used for assignment, while == is for loose equality comparison, which involves type coercion. ===, on the other hand, performs a strict equality comparison without any type coercion.

To fix your code, you need to replace = with == or === in your equality comparisons. For instance, instead of:

if (str = '') {}

Use:

if (str == '') {}

or

if (str === '') {}

By using == or ===, you ensure that the equality comparison is correct and that your code functions as intended.
