𝗪𝗵𝗮𝘁 𝗶𝘀 𝗖𝗿𝗼𝘀𝘀-𝗢𝗿𝗶𝗴𝗶𝗻 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲 𝗦𝗵𝗮𝗿𝗶𝗻𝗴 (𝗖𝗢𝗥𝗦)?

Browsers use CORS, a method, to prevent websites from requesting data from different URLs. A request from a browser includes an origin header in the request message. The browser allows it if it gets to the server of the exact origin; if not, the browser blocks it.

We can deal with CORS issues on the backend. Cross-origin requests require that the values for origin and 𝗔𝗰𝗰𝗲𝘀𝘀-𝗖𝗼𝗻𝘁𝗿𝗼𝗹-𝗔𝗹𝗹𝗼𝘄-𝗢𝗿𝗶𝗴𝗶𝗻 in the response headers match and it is set by the server. When you add an origin to the backend code, the CORS middleware only permits this URL to communicate with other origins and utilize it for cross-origin resource requests.

There are two ways to fix CORS issues:

𝟭. 𝗖𝗼𝗻𝗳𝗶𝗴𝘂𝗿𝗲 𝘁𝗵𝗲 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝘁𝗼 𝗔𝗹𝗹𝗼𝘄 𝗖𝗢𝗥𝗦

Server can let all domains with 𝗔𝗰𝗰𝗲𝘀𝘀-𝗖𝗼𝗻𝘁𝗿𝗼𝗹-𝗔𝗹𝗹𝗼𝘄-𝗢𝗿𝗶𝗴𝗶𝗻: *. This actually turns off same-origin policy, which is not recommended. Another option would be only to allow particular domain, which is better option, e.g., 𝗔𝗰𝗰𝗲𝘀𝘀-𝗖𝗼𝗻𝘁𝗿𝗼𝗹-𝗔𝗹𝗹𝗼𝘄-𝗢𝗿𝗶𝗴𝗶𝗻: 𝗵𝘁𝘁𝗽𝘀://𝘀𝗼𝗺𝗲𝗱𝗼𝗺𝗮𝗶𝗻.𝗰𝗼𝗺.

𝟮. 𝗨𝘀𝗲 𝗮 𝗣𝗿𝗼𝘅𝘆 𝗦𝗲𝗿𝘃𝗲𝗿

We can use a proxy server to call external API. It acts as a middleware between client and the server. If server doesn't return proper headers defined by CORS, we can add then in the proxy.

Elements :- it is a javascript object
it is used in the document that are represented Html tags <p> , <div> <span>

attributes :- properties of elements which can be manipulated or accessed ex:- id class style or src

span tag:- inline container
used to markup text , documents
manipulation of css with the help of javascript

outline css :-it is used to create line around html elements

syntax :- element {outline :<outline-style><outline-width><outline-color>;}


div {outline :solid 10px #000000;}

inline css:- style attributes of html elements
used to apply unique styling to a single elements
it is used to directly define within the start tag
example :- <p style ="color:red; font-size :10px ;width:20px"> This is a paragraph </p>


Html tags :- define the structure & content of web-page

<html>
<head>
<title> My webpage </title>
</head>
<body>
<h1> welcome to my webpage </h1>
<p> welcome to my webpage </p>
<ul>
<li> first item </li>
<li> Second item </li>
</ul>
<a href ="http://www.example.com">Link to another page </a>
</body>
</html>



selectors in css ?

used to select html elements that you want to style
or you can say patterns used to identify the elements you want to style

id selctors :- can be used only on tags defined with id attributes
class selectors :- can be used only on tags defined with class attributes
universal selectors :- can be used on all elements on the defined page




this keyword in javascript?

refer the object it belongs to
it can be used inside the function
it can be used to access the objects properties and methods


let and var keyword difference

var is function scoped (this means var can be accessed outside the block it is declared in )VARIABLE HOISTING
let is block scoped ( this means let can be accessed inside the block it is decalred in ) NOT ALLOWED VARIABLE HOISTING


Components :- it is a building block of react application
these are reusable piece of code that can be composed to create complex user interface


for-of :- looping construct used to iterate over an iterable object
such as array , string , set

var String = hello;
for(const letter of string){
console.log(letter);
}


for-each :- looping construct used to iterate over an collection of object
it is used to iterate on each collection


example:- var array =[1,2,3,4,5];
array.forEach(function(item){
console.log(item);
}


forms in html is used to take input from user
it consists of checkbox , radio buttons or select buttons

action
method
target response coming from server will be displayed
enctype type of encoding used to submit the form data
autocomplete whether or not form data will be saved by browser or not
novalidate whether or not form data will be validated by browser or not
accept-charset it will specify the character encoding used to submit form data


DOM :- it is a library
it gives specific methods
it is the entry point for working with dom in react
it reduces the amount of time used to render for a page

when we want to switch from one statement or to break the loop or label the statement


example for(let i = 0; i<100;i++){
if (i===5){
break;}
console.log(i)}
// output : 0,1,2,3,4
