In TypeScript, the ‘object’ type is a type that represents all non-primitive types. The ‘object’ type is assignable to very few other types because it is a very general type and not specific to any particular object shape or structure. It is often used when you want to indicate that a value can be of any type other than the primitive types (boolean, number, string, null, undefined, symbol).
It seems that you might have intended to use the ‘any’ type instead of the ‘object’ type. The ‘any’ type is assignable to all other types, including both primitive and non-primitive types. It provides flexibility but also removes some of the type-checking benefits that TypeScript offers.
Here’s an example to illustrate the difference between the ‘object’ and ‘any’ types:
// Declaring a variable with the 'object' type
let obj: object;
// Assigning an object literal to the variable
obj = { name: 'John', age: 30 };
// Accessing properties of the object
console.log(obj.name); // Error: Property 'name' does not exist on type 'object'
// Declaring a variable with the 'any' type
let anyValue: any;
// Assigning an object literal to the variable
anyValue = { name: 'John', age: 30 };
// Accessing properties of the object
console.log(anyValue.name); // No error
// Assigning a primitive value to the variable
anyValue = 'Hello';
// Accessing properties or methods of the primitive value
console.log(anyValue.length); // No error
As shown in the example, when using the ‘object’ type, TypeScript enforces stricter type-checking and does not allow accessing properties or methods that are not defined on the ‘object’ type itself. On the other hand, the ‘any’ type allows accessing any property or method without type-checking.
