First, determine the number of files to display per page, then calculate the start and end indices for slicing the file array. Use Array.slice() to get the current page's files and render them in the desired HTML structure. Finally, implement navigation buttons to update the current page and re-render the files accordingly.

When is it best to teach handwriting script?

It is best to teach handwriting script around ages 6 to 8, when children have developed sufficient fine motor skills and cognitive abilities to understand letter formation. At this stage, they are typically transitioning from learning to print to writing more fluently. Introducing cursive in this period can help reinforce letter connections and improve writing speed. However, individual readiness may vary, so it's essential to consider each child's unique development.

Is pascal supports static binding and dynamic binding?

Yes, Pascal supports both static binding and dynamic binding. Static binding occurs at compile time, typically with procedures and functions that are known at that time. Dynamic binding, on the other hand, is often associated with objects in object-oriented Pascal, where method calls can be resolved at runtime based on the actual object type. This allows for polymorphism, enabling more flexible and reusable code.
