   In react we can achieve lazy loading after performing some steps. Let's start Step 1:- We need to import the Suspense component  - Now here I have imported Suspense component from react          import React, {Component, Suspense} from 'react'; Step 2: We need to change the way of importing Component in React - Now we are importing our other components here. I'm importing the Login and register component here. - Here we are using React.lazy() method  const Register = React.lazy(() => import('./containers/auth/register/register')) const Login = React.lazy(() => import('./containers/auth/login/Login')) Step 3: Now we need to declare our routes   Here we are using Suspence for declaring component.  <Route path={'/'} render={() =>  <Suspense fallback={<div>Loading....</div>}>             <Login />           </Suspense>} exact/>         <Route path={'/register'} render={() =>           <

Hey Guys, in this blog we are going to learn about What is the different between   LET and CONST key word ( ES 6)    with examples  Let's get started... LET: Let  key word now we are using for  declaring variables . It's not like a surprise because it's come with improvement of  VAR  keywords. In  Let , we can declare variables like we are declaring using the  VAR keyword  but in  LET  keyword we cannot re-declare that variables like below. but we can change the value of variable like beow CONST: In  CONST  keyword we are using when we have  static value.  Let assume you have one value that  not going to change anywhere in the function of the file  in that case we can use  CONST  Keywords. we can not re-declare const variable and we can not update const keyword value like below. but we can use it like below. If you guys have any query then you can drop a mail to us on this mail id: techoswag@gmail.com

  Hey Guys, in this blog we are going to learn about What is Java Script Arrow Functions and how we can use it. Let's get started... - Arrow function has been introduced in the ES 6. - Arrow function allow us to write function shortly and simply. Arrow function looks like below const funcName = (arg1, arg2, arg3, ..., argN) => expression - Basically above expression means is it creates a  function  with  name: funcName  with the  arg1, arg2, ar3,...,argN  and after that, it's evaluate the  expression  and  return the results . - Let's take a simple example let's print the sum of two number using arrow function. In this example as you can see here function name is  sums  and it's take  two arguments x and y   and it's evaluate  expression ( x+ y )  and based on evaluation it will return result so here it will return  result 25. - Suppose if in any example if we have only  one parameter  so in that case we can  omitted parentheses  from pa
