funThis - any: the functions ‘this’ object
functionName - string: name of the contract function to call
...args - any: any addtional parameters that should be passed to the called function

  .then(content => console.log('file content: ' + content))

utils.obfuscate(text);

const obfuscated = runtime.utils.obfuscate('sample text');
