      ​​@@manoyalSee there is two thing
      One is Pura Javascript and it hole about js.
      And second is DOM we use DOM to manipulate the thing on web pages like style, action, on click action.
      Here he will tell Basic of Js which is imp than he will Start DOM.
      Only Basic of Js will be covered. If you want to learn more moderate level and advance level of js than you can go with particular course of js

    The reason why the type of null is an object in JavaScript is a historical decision that has been maintained for compatibility reasons. When JavaScript was first created, there was no separate type for null, and it was simply treated as a special case of the object type. This was because null was often used to represent an empty reference to an object, and it made sense to treat it as such from a programming perspective.
    Over time, JavaScript has evolved to include a separate type for null, but the original behavior of returning object for typeof null has been preserved to avoid breaking existing code. This is a common practice in software development, as it is often more important to maintain compatibility with existing code than to make changes that could break it.
    As a result, the type of null is still considered to be an object in JavaScript, even though it is technically a separate type. This can be a bit confusing for some developers, but it is important to understand the historical context behind this behavior.
