};
===END OPTIONS===
function getAreaOfCircle(radius) {
  var pi = Math.PI;
  var radiusSquared = Math.pow(radius, 2);
  var area = pi * radiusSquared;

  return area;

Usage Example

The provided code example will obfuscate the file input.js and write the output to a file named output.js. 
import JSConfuser from "js-confuser";
import {readFileSync, writeFileSync} from "fs";

// Read input code
const sourceCode = readFileSync("input.js", "utf8");
const options = {
  target: 'browser',
  movedDeclarations: true,
};

JSConfuser.obfuscate(sourceCode, options).then((result)=>{
  // Write output code
  writeFileSync("output.js", result.code);
}).catch(err=>{
  // Error occurred
  console.error(err);  
});
