JavaScript Runtime Explained: All you need to know about client-side JS code execution |

JavaScript Runtime Explained All you need to know about client side JS code executionIf like me you struggled to understand the concept of the JavaScript runtime this article may help shed some light on this particular topic Put simply the JavaScript runtime is the environment that executes your JavaScript code Although JavaScript can now be run on the server side Node js Deno today we will focus on the client side running JavaScript in the browser The browser does not have the ability to understand JavaScript files Instead they must be parsed into executable commands In order to do this the browser uses a JavaScript engine for instance Chrome uses the Google V engine The specific engine depends on which browser you re using Here s a list of browser specific engines Components of the JS runtimeIn the browser world the JavaScript runtime environment is made up of the following Call Stack part of the JS engine The call stack makes up part of the JS engine As the name suggests it s a stack data structure which keeps track of which functions are running This is emblematic of the single threaded nature of JavaScript as being a stack the call stack can only handle one function at a time The call stack follows a last in first out principle In order to facilitate asynchronous code callback and microtasks queues are implemented see below Memory Heap amp Memory Stack part of the JS engine Another piece of the JS engine is the memory heap stack which is responsible for allocating space for any data in your JavaScript file Depending on the type of data the JS engine will allocate space in either the memory heap or the memory stack The memory stack is reserved for static data such as primitive values or references to objects functions data which the JavaScript engine knows the size of at compile time On the other hand the memory heap is where the objects and functions themselves are stored At compile time the JavaScript engine does not know the size of these pieces of data and will not find out until run time so the memory space allocation is more dynamic Web APIs supplied by the browser Web APIs are separate from the JS engine and are provided by the browser To quote Will Sentance they are “facade functions which look like JS functions and which can be interacted with in your code but they are not native to the JavaScript language One example is the DOM API which allows you to interact with the HTML of the web page Other examples include setTimeout fetch local storage interface and event listeners Callback Queue supplied by the browser The callback queue takes care of executing callback functions in the correct order by pushing them to the call stack when their time comes It operates on a first in first out basis An example could be timer related functionality such as setTimeout or setInterval Microtask Queue supplied by the browser Similarly the microtask queue also deals with sending callbacks to the call stack What s the difference The microtask queue handles callback functions coming from promises queueMicrotask invocations and mutation observers The microtask queue takes priority over the callback queue so the callback queue will have to wait for the microtask queue to be empty before it can send anything to the call stack Event Loop supplied by the browser The event loop is the middle man between the callback microtask queues and the call stack It keeps track of what is in the callback microtask queue and sends the relevant function to the call stack As mentioned above it prioritises the microtask queue and will only send callback queue functionality to the call stack once the microtask queue is completely empty Now let s put it into practice setTimeout gt console log ahoj console log hola OUTPUT gt hola ahojIn the snippet above the console log hola will be executed first because the setTimeout function will be sent to the callback queue as it s utilising the timer from the Browser API Even though the timer is set for seconds it waits for the call stack to be empty before triggering setTimeout gt console log ahoj Promise resolve hi then val gt console log val console log hola OUTPUT gt hola hi ahojIn this second example as with the above the console log hola runs first The promise comes second as this is sent to the microtask queue which takes precedence over the callback queue Finally the setTimeout callback runs after the microtask is clear and the callback queue functions are pushed to the call stack by the event loop In the case of fetch and setTimeout you might get a different order to the one you were expecting This is due to the fact that the microtask queue may be empty if it s still waiting for the response from the XHR request meaning that a setTimeout with a timer set to ms could potentially run first fetch then res gt res json then data gt console log data setTimeout gt console log ahoj OUTPUT gt ahoj Response Object Here s a great video summary of the topic |
