The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScriptâs output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details.

JSDefender
PreEmptive
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. -
