An object literal cannot have multiple properties with the same name.

In JavaScript, an object literal is a comma-separated list of name-value pairs wrapped in curly braces ({ }).
Each name-value pair represents a property, where the name is a string (or a symbol) and the value can be of any data type.
An object literal cannot have multiple properties with the same name because each property name must be unique within the object.

If you try to define multiple properties with the same name in an object literal, it will result in a syntax error.
For example:

  
  const myObj = {
    prop1: 'value1',
    prop2: 'value2',
    prop1: 'value3' // Syntax error: Duplicate property name 'prop1'
  };
  
  

In the above code snippet, the object literal “myObj” contains two properties with the name “prop1”.
This is not allowed and will throw a syntax error because property names must be unique within an object.

To resolve this issue, you can either provide unique names for each property or use a different data structure such as an array or Map if you need to store multiple values with the same identifier.

Here’s an example of using an array to store multiple values with the same identifier:

  
  const myArr = [
    { prop: 'value1' },
    { prop: 'value2' },
    { prop: 'value3' }
  ];
  
  

In the above example, instead of using an object literal, we created an array “myArr” that contains three objects.
Each object has a unique index in the array, and the “prop” property in each object can store different values.
