This array is then serialized through JSON and stored in a cookie. In the shopping cart interface, y

Definition: Programming skills called by the program itself are referred to as recursion. A procedure or function has a method of directly or indirectly invoking itself in its definition or description, which usually transforms a large and complex problem layer into a smaller problem similar to the original problem, and the recursive strategy can describe the repeated computations needed in the process of solving the problems by a small number of programs. Greatly reduces the code volume of the
