ALT // What's the difference between any and unknown in TypeScript? let anyValue: any; let unknownValue: unknown; // Try and call them as functions anyValue(); // anything goes with any! unknownValue(); // Does not work // unless we check the type if (typeof unknownValue === 'function') { unknownValue(); // then it works! } // Same with other types, like numbers: anyValue++; // anything goes! unknownValue++; // not a number! // We can also assert an unknown to make it work (unknownValue as number)++; // TLDR: unknown is a bit more type safe and // makes you check the type before using it
