An array declaration allocates sequential memory blocks. File C:\Users\SHUBHAM KUNWAR\AppData\Roaming\npm\nodemon.ps1 cannot be loaded because running scripts is disabled on this system. This post focuses on the practical aspects of the unknown type, including a comparison with the any type. if an array contains primitive types, it is very easy to filter Duplicates if an array contains objects, We need to filter the duplicates based on key and value pair equal validation. A ball is fired from a sling shot. We don't get a lot of protection from TypeScript if we're opting to use any. function should take three arguments - operation(string/char), value1(number), value2(number). If the item doesn't exist or isn't valid JSON, the function should return an error result; otherwise, it should deserialize and return the value.
