Which are the best online coding tutorials through which I can introduce my child to coding. Is 6-year too young to introduce her to coding?

I don't think coding tutorials can help you as much as the https://processmix.com/cases/assignment-of-risk-level-and-customer-category-within-kyc-processes-at-customer-onboarding/ platform. This low-code platform is suitable for running decision logic models as a set of business rules. For example if you're having some problems optimizing things with the bank. It will also allow you to create your own or use already created predictive models.
