Is obfuscated JavaScript slower?
It certainly does slow down the browser more significantly on older browsers (specifically when initializing), but it definitely slows it down even afterwards.
Can JavaScript be hacked?
One of the most sneaky uses of JavaScript is cross-site scripting (XSS). Simply put, XSS is a vulnerability that allows hackers to embed malicious JavaScript code into an legitimate website, which is ultimately executed in the browser of a user who visits the website.
Why should programmers avoid obfuscated code?
While obfuscation can make reading, writing, and reverse-engineering a program difficult and time-consuming, it will not necessarily make it impossible. It adds time and complexity to the build process for the developers. It can make debugging issues after the software has been obfuscated extremely difficult.
What are the ways to hide your code?
“JavaScript Encryption” This is by far the most popular way to try to hide one’s source code. It involves taking your code, using a custom made function to “encrypt” it somehow, and then putting it in an HTML file along with a function that will decrypt it for the browser.9 Apr 2010
Should JavaScript be obfuscated?
Advantages of obfuscating JS Prevent people from copying or modifying your code without authorization. The obfuscated JavaScript will be way larger and difficult to understand.
Can you read obfuscated code?
So, with obfuscation, the browser can access, read and interpret the obfuscated JavaScript code just as easily as the original, un-obfuscated code. And even though the obfuscated code looks completely different, it will generate precisely the same output in the browser.
How do I hide the code in inspect element?
You simply can’t. Code inspectors are designed for debugging HTML and JavaScript. They do so by showing the live DOM object of the web page. That means it reveals HTML code of everything you see on the page, even if they’re generated by JavaScript.
Is code obfuscation important?
Obfuscation of code is especially important for open-source systems, which have a significant disadvantage in code hackability for personal gain. Obfuscation is especially important for source code that is distributed insecurely.27 Aug 2021
Can JavaScript be protected?

The goal of code obfuscation is to prevent any unauthorized party from accessing and gaining insight into the logic of an application, which prevents them from extracting data, tampering with code, exploiting vulnerabilities, and more.
Is obfuscated code safe?
Obfuscating your code will raise the bar for who can decompile your code and reduce the likelihood of an attacker being able to quickly and easily Trojan your binaries. However, like most things, as a single line of defense it is far from sufficient.
Do you need obfuscation?

Why is Code Obfuscation Required? Code obfuscation is particularly useful for open-source applications, which pose a huge disadvantage in terms of hackability of code for personal gains.
What is JavaScript security?
JavaScript security is related to investigating, preventing, protecting, and resolving security issues in applications where JavaScript is used.
