strict mode or not ?

[noble hinge]

we are a team where I am the only one who knows angular.
we are working on a large project which is ending or strict mode has been deactivated. to simplify, we don't use NGRX either but service+ behaviorsubject
the application runs very well.

we are going to start a new project and I am wondering whether or not to activate strict mode knowing that most devs are beginners.

what would you do?

Do activate it. It's the default, and it's safer. But if they're not used to a language where null/undefined are their own type, teach them what it means. Teach them when it's better to check for null, or to use the null-safe operator, or the ! operator.
