About

Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities.

About

JavaScript is a scripting language and programming language for the web that enables developers to build dynamic elements on the web. Over 97% of the websites in the world use client-side JavaScript. JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.
