wrap all console log methods with a specified prefix

pconsole.js

// Note: relies on es6 for..of loop and ..., the 'spread' operator; can easily be adapted to es5
function pconsole(prefix /* string */) {
  // preserves original line number of calling function
  // usage:
  // const todo_console = pconsole('TODO');
  // todo_console.log(1, 2) outputs 'TODO 1 2' and similar for debug, info, warn, etc... methods
  const prefix_console = {};
  const log_methods = ['debug', 'dir', 'error', 'exception', 'info', 'log', 'table', 'trace', 'warn'];

  for (let method of log_methods) {
    prefix_console[method] = window.console[method].bind(window.console, prefix);
  }
  return prefix_console;
