Code Inspection: Equality operator may cause type coercion

Reports usages of equality operators which may cause unexpected type coercions. It is considered a good practice to use the type-safe equality operators === and !== instead of their regular counterparts == and != .

Depending on the option selected, this will either highlight:

  • All usages of == and != operators.

  • All usages except comparison with null. Some code styles allow using x == null as a replacement for x === null || x === undefined .

  • Only suspicious expressions, such as: == or != comparisons to 0 , '' , null , true , false , or undefined .
