What does it mean by Javascript is single threaded language

If you have been using Javascript for a while then you may come across the phrase that it’s a single threaded language.

What does that means?

Javascript engine runs on a V8 engine that has a memory heap and a call stack.

JS is a single threaded which means only one statement is executed at a time.

Before we dive into what it means by it runs on single thread. I would want to first go over the terminology that will help you in understanding.

My attempt will be to explain in the simplest manner possible. To understand this better you need to know a Data Structure known as Stack (Last In, First Out).

Synchronous (or sync) execution usually refers to code executing in sequence. In sync programming, the program is executed line by line, one line at a time. Each time a function is called, the program execution waits until that function returns before continuing to the next line of code.

To put it in example, you are calling someone and you’re waiting for them to pick up so that you can talk to them. You’re not doing any other thing until they pick up the phone.

You fulfill the request sequentially.

const one() => {
const two() => {
console.log('5');
}
two();
}

So, what happens under the call stack?

The call stack job is to fill in the instructions and pop an instruction as it gets executed.

Javascript is a single threaded language that can be non-blocking. Single threaded means it has only one call stack. Whatever is on the top of the call stack is run first.

In the above program, functions are run sequentially.

What if we have a function that is require to do heavy lifting. Should we let the user wait till that process is over?

const one() {
console.log("Hello");
}
const two () {
for(i=0; i<= 100000000000000000000000; i++){
}
const three(){
console.log("World");
}
one();
two();
three();

Consider the above example, what if our second function has to loop through huge numbers. Does this means three() has to wait till two() is executed. Technically, Yes!

In our small example it may not mean much but if we have to implement in a real project then the users may not be able to do anything until the first process is finished.

Asynchronous (or async) execution refers to execution that doesn’t run in the sequence it appears in the code. In async programming the program doesn’t wait for the task to complete and can move on to the next task.

To put it in example: You call someone and while you’re waiting for them pick up the phone, you’re also running errands.

Different languages have different ways to implement asynchronous. The most popular is through Multi-threading.

In brief, Java implements multi-threading by creating a child thread which does it’s own separate execution and then merges back with the parent thread. This however can run into a problem known as Deadlock, which can be dealt with various deadlock prevention mechanism.

Since, we are concerned about implementing asynchronous in Javascript. Let’s see how we can do it.

Try running this in console and see what happens.

console.log('1');
setTimeout(()=> {
console.log('2')
}, 3000);
console.log('3');

You may see 1 3 and with a brief delay 2 shows up. Why is this happening?

In Javascript, All instructions are put on a call stack. When the stack arrives at setTimeout, the engine sees it as a Web API instruction and pops it out and sends it to Web API. Once the Web API is done with the execution, it will arrive at the call back queue.

The engine checks if the call stack is empty. If it is empty, then we check callback queue which has the instruction setTimeout in it. The callback queue sends it to call back stack and the instruction is executed.

The other way to think about this is when you make an API request. Say for example your website needs to fetch an image from a server. Should your website refuse to load other parts till the image arrives? That would be a bad user experience.

When call stack sees it needs to fetch an image, it pops and send it to Web API and continues executing the remaining functions.

The response of image request is stored in call stack queue.

When the call stack is empty, the event loop which is continuously running looks over the Call stack queue if it has anything. If it does, in our case the response of image request. It puts over the call stack and execute the instruction.

The benefit of this procedure is JavaScript need not worry about how many cores or nodes a CPU is running on. There is only single call stack for this implementation.

The Single Best WordPress Plugin Across Every Essential Category

WordPress powers 30% of the top 10 million websites. It controls more than 60% of the of the CMS platform market share.

Needless to say, it’s a popular solution for running a website. WordPress itself is great; but it’s limited in terms of its built-in functionality.

That’s why plugins exist.

What exactly is a WordPress plugin?

It’s essentially an app for your website.

I love how WordPress is designed to be lean out of the box. This prevents code bloat — your website isn’t dragged down by bulky code for things you don’t need or use. The core of WordPress is simple. You can customize it with plugins.

The core of WordPress is designed to be lean and lightweight, to maximize flexibility and minimize code bloat. Plugins then offer custom functions and features so that each user can tailor their site to their specific needs.— WordPress Codex

Installing a plugin to your WordPress site provides you with advanced features that aren’t available with the bare bones version of WordPress.

Where can you get a plugin? There are a number of places, but the primary source is the Official WordPress Plugins Repository.

In-Depth Reviews of the Best WordPress Plugins in 13 Categories

In the official repo you’ll find a plugin for nearly every feature you can imagine. Actually, there are hundreds of plugins for each specific function. As a matter of fact, there are more than 54,300 WordPress plugins. It’s an overwhelming number to say the least.

That’s why I took the time to identify the best WordPress plugins for the most popular categories. I’ve already created extensive guides for each one of these 13 categories. Every guide contains a list of the best WordPress plugins in each segment. And if you’re after something specific, you should check out that post — many of plugins I recommend are for particular use cases.

This my the complete list of my in-depth plugin reviews for…

The Best of the Best WordPress Plugins

Each of those posts reviews multiple plugins in each category. But most people don’t need to go that deep. That’s why I made this best of the best list. This is a resource to identify the top must-have plugin for each category.

Conclusion: What’s the best WordPress plugin?

These are the best overall options for each of the essential categories. Keep in mind, I identified these as the best because they appeal to the widest possible audience. Some of you may want plugins that have more specific features and functionality within each category.

For example, you might want an SEO plugin that specifically helps you identify relevant keywords while you’re blogging. Or maybe you want a social media plugin that just adds your Instagram feed to your website.

Do you want a Google Analytics WordPress that’s made for tracking specific events on your website? There’s a plugin for that too.

There are caching plugins that are better for things like the cloning and migrating content between servers. The list goes on and on.

So I’d definitely recommend reviewing the individual guides for each category as well. That way you’ll know for sure that you’re installing a plugin that meets your specific needs.
