Profile of Software Companies of Bangladesh I wanted to write an article that would list down the profiles of various software companies of Bangladesh. So, I had created a form to collect this information. The responses are as follows:

Nullish coalescing operator '??' vs Logical OR operator '||'
The major difference between them is that:
|| returns the first truthy value.
?? returns the first defined value.
Example:
const marks = 0;
console.log(marks || 100); // 100
console.log(marks ?? 100); // 0
sometimes we have to consider 0 or ' ' as valid, then the ?? operator works better.

To learn more to code, one piece of advice is more important than anything else:
Write lots of code.
You won't become developer-only by watching tutorials and reading articles.
You have to put in the work, get your hands dirty, and build stuff.
By building lots of projects, your skills will accumulate quickly and you'll begin to recognize patterns.
And if you can get into the habit of coding every single day, success is basically inevitable.
There are 9 HTTP request methods:
- GET
- PUT
- POST
- HEAD
- TRACE
- PATCH
- DELETE
- OPTIONS
- CONNECT
HTTP request methods are the actions initiated from the client-side to perform certain actions.
These HTTP request methods are sometimes called nouns or referred to as HTTP verbs.
The GET method is the most common of all these request methods. It is used to get the desired resources from the server.
The GET methods don't affect the state of the server.
The POST method is used to submit the information to the server. As we're submitting data, the POST method often changes the state of the server.
The PUT method is used whenever you need to change the resource. The resource is already a part of resource collection.
The PATCH request method is used to modify only the necessary part of the data or response. The PATCH method doesn't modify the entire response.
The server sends the response without the body. The HEAD method asks for a response identical to that of a GET request, but it is faster as small data is transferred.
As the name says, the DELETE request method is used to delete the specified resource. It requests that the origin server delete the resource identified by the Request-URL.
The CONNECT method establishes two-way communication between the client and the requested resource.
CONNECT request method is used to push your proxy to start an HTTP tunnel.
The OPTIONS method is used to describe the communication options available for the target resource. The client can either specify a URL for describing the communication options available for a specific resource or an asterisk (*) if they want to target the server.
The TRACE method is generally used for debugging. It performs a message loop-back test along the path to the desired data.
