Error message

Using the loose equality operator (==) can lead to unexpected results due to type coercion. Developers are generally encouraged to use strict equality (===).

What broke

The code is using the loose equality operator (==) which allows for type coercion between different data types. This can lead to results that are not intuitive, making debugging difficult.

Why it broke

Loose equality checks can produce unexpected results because JavaScript attempts to convert the values to a common type before comparing them. This behavior can lead to false positives in comparisons, especially when comparing different types like strings and numbers.

How to fix

Replace all instances of the loose equality operator (==) with the strict equality operator (===). This ensures that both the value and the type are compared, preventing any unintended type coercion.

Code fix

if (a === b) { /* code */ }
