Applications Of Artificial Intelligence
Artificial Intelligence is gradually entering our homes, offices, workspaces, playgrounds, transports, and even predicting weather phenomena. Almost all global organizations today are leveraging the benefit of AI technology for specific interests. AI-based automated machines are now used across multiple verticals for complex tasks that need more precision.
Here are some of the major commercial uses of AI in real-world applications:

Rewriting a Regular Function with ES6 Arrow Syntax
Here’s a standard way to declare a function and then call it in JavaScript:
// function declaration
function sayHiStranger() {
return 'Hi, stranger!'
}
// call the function
sayHiStranger()
You can also write the same function as a function expression, like this:
const sayHiStranger = function () {
return 'Hi, stranger!'
}

Explain nodejs?
Node.js is an open source server side runtime environment built on chrome's V8 JavaScript engine. It provides an event-driven, non-blocking (asynchronous) I/O and cross-platform runtime environment for building highly scalable server side applications using JavaScript.
Node.js is made of Chrome V8 engine which is written in C++ and Libuv which is a multi-platform C library that provides support for asynchronous I/O based events on event loops and thread loops.
<?php
$a=3;
$b=$a++;
$c= ++$b;
echo $a."--".$b."--".$c; //output: 4--4--4
?>

<?php
$a="10 ear";
$b="11 ear";
$c= $a+$b;
echo $c; //output: 21
echo "10 ear" + "10 ear"; //output: 20
echo "10 ear" + "ear 10"; //output: 10
echo "ear 10" + "10 ear"; //output: 10
echo "ear 10" + "ear 10"; //output: 0
?>
