在 class model.js 中调用 function

Question

I have 2 functions inside model.js, findUser(id) and findById(userId). they are both inside class. Inside findById(userId), I want to call findUser(id). how can I do that?

findUser(id) {
                let foundUsers = users.filter(function(user) {
                    if(user.id === id) {
                        return true;
                    }
                    return false;
                });
    
                if(foundUsers.length > 0) {
                    return foundUsers[0];
                } else {
                    return null;
                }
            }
    
    
    
         findById(userId) {
            // Find user by Id
            // Returns user, or null if not present
    }

Answer 1

I think you would need to use "this".

Answer 2

Usually it's not a good practice to call a method inside a model class. So better create a model object out side and call each functions accordingly.

Create a new object of that class

let model1 = new Model();

Call that function using dot operator.

model1.findUser(id);
model1.findById(userId);
