A type literal property cannot have an initializer.

In JavaScript, a type literal property is defined using the object literal notation. This means declaring a property within an object without specifying any particular data type. However, a type literal property cannot have an initializer, meaning it cannot be assigned a default value during declaration.

To clarify, here is an example:

    
      var person = {
        name: "John",  // This is a type literal property with an initializer
        age: 28,  // This is a type literal property with an initializer
        address  // This is a type literal property without an initializer
      };
    
  

In the example above, the “name” and “age” properties are type literal properties with initializers, as they are assigned values during declaration. However, the “address” property is a type literal property without an initializer, as it does not have a default value.

If you try to assign an initializer to a type literal property, such as:

    
      var person = {
        address: "123 Street"  // Invalid: type literal property cannot have an initializer
      };
    
  

You will encounter an error indicating that a type literal property cannot have an initializer. To fix this issue, you should assign a value to the property separately after the object is created or by using variable assignment during declaration, like:

    
      var person = {
        address: null  // Assigning a default value or undefined if no initial value is intended
      };
      
      // Assign address value separately
      person.address = "123 Street";
      
      // Using variable assignment during declaration
      var address = "123 Street";
      var person = {
        address: address  // Assigning the value of the separate variable
      };
    
  

By applying these solutions, you can declare type literal properties without initializers in JavaScript objects.
