Why is string considered as an object in JavaScript?

Strings are objects in JavaScript because they are a collection of characters and objects can have properties and methods. Strings can have methods such as charAt(), indexOf(), and slice(). These methods allow you to manipulate the string, such as getting a character at a specific index, finding the index of a character, or slicing a section of the string.
In JavaScript, strings are not objects in the strictest sense. They are primitive values, which means that they are not objects themselves. However, JavaScript automatically wraps string primitives in String objects when you try to access their properties or methods. This means that you can use the same syntax to access the properties and methods of string primitives as you would for String objects.

There are a few reasons why JavaScript strings are objects. First, it allows you to use the same syntax to access the properties and methods of string primitives as you would for String objects. This makes it easier to learn and use JavaScript. Second, it allows you to add new properties and methods to strings. This can be useful for extending the functionality of strings. Finally, it allows you to use the prototype chain to inherit properties and methods from other objects. This can be useful for reusing code.
