Equality

In Mint, 2 objects are considered equal if they have the same type and all values are equal. The equality operator is ==.

These examples all evaluate to true:

{ name = "Jon Doe", age=27 } == { age=27, name = "Jon Doe" }
Maybe.just("A") == Maybe.just("A")
["A"] == ["A"]

In JavaScript, the same == comparison would return false. We say Mint uses "logical" equality.

In addition to records and enums, the following types use logical equality:

• String
• Number
• Boolean
• Array
• FormData
• Date
• Maybe
• Result
• Map
• Set
• SearchParams

Types that have not implemented the logical equality operation fall back to using the JavaScript strict equality operator ===
