};In your code, add prefixes to the words that you want Codefend to encrypt.
Make sure to read the Philosophy behind Codefend obfuscation First to understand why Codefend can work with any code written in any language.
//node js example
//as a starting point: prefix the words that should be encrypted with l_
class l_Calculator {
l_sum(l_a, l_b) {
const l_results = l_a + l_b;
console.log("node_modules");
return l_results;
}
}
//>>>>>>==== Will Become ======<<<<<<
class Ox0 {
Ox1(Ox2, Ox3) {
const Ox4 = Ox2 + Ox3;
console.log("node_modules"); // will not be obfuscated as it is added to ignoredWords in Codefend options
return Ox4;
}
