The only code that's specific to SweetAlert is the tActionValue() and the swal() call at the end.

We then extract its DOM node and pass it into under the swal function's content option to render it as an unstyled element. All we're doing is creating an input tag as a React component. React.js īut if you want to add a class in the list() element then we could’ve added the second property as: const listElement = React.This might look very complex at first, but it's actually pretty simple.

So we pass the text as a string.ĭuring the rendering process, React converts the React element to the actual DOM element. In the list node, we don’t have children to insert, but we do have the text. Any node that is inserted in between the starting tag and ending tag should be defined in the third parameter.

React.js: The third element represents the element’s children.

So we’ve to externally pass null if there is no property. We could have passed the className property to it, to define the class property on the list node.

null: We don’t want to define any property in the list element.

li: It defines the type of element we want to create.

It could be the content of a node.Įxample: How to create a li element in our application: const listElement = React.createElement( 'li', null, 'React.js' ) Įxplanation: In the above code, we passed 3 arguments to createElement which are as follows:

children or content: There are children or content to display other nested elements.

props: It is a JavaScript object that contains properties or data required to construct a DOM.

type: It is the type of element you want to create i.e.

Parameters: Above method accepts the following parameters: We can create a React element using React’s createElement method. The React element is just a JavaScript object that describes the DOM element in memory. Both look exactly the same, but they are quite different.Īs already described earlier, the React element is the smallest entity. DOM is made up of DOM nodes/elements and React is made up of React nodes/elements. There are some similarities between DOM and React. React will take care of rendering and reconciling the element for us through the command we give to react.

From now onwards we don’t update DOM directly instead we’re going to tell react to update the DOM for us. React is a library that is specifically designed to interact with DOM for us. So to overcome complexity we’re going to use React to handle complexity for us. If you want to build the HTML page, we can also build with vanilla JavaScript.īut as our application grows, complexity grows, and it is hard to maintain. The manipulation here means CRUD(create, read, update, and delete) operations in DOM nodes. The DOM API is just a collection of objects that JavaScript uses to manipulate the DOM. JavaScript uses DOM API to updates and manipulates DOM nodes. It is JavaScript that is doing heavy lifting under the hood. JavaScript destroys the old and creates a new UI. But the user always stays on the same page. It feels like the user is jumping from page to page. When a user navigates by clicking the links, the browser sends the request and then the browser updates the part of a DOM. In SPA, the browser first loads the initial HTML document. But after the invention of AJAX(Asynchronous JavaScript and XML) brought us a single Page Application(SPA). In the past, websites consisted of multiple pages, and when the user clicks on a link then the browser requests a new HTML page and builds DOM again.
