bindAll

Explain briefly what the snippet does.

Use Array.forEach() to return a function that uses Function.apply() to apply the given context (obj) to fn for each function specified.

const bindAll = (obj, ...fns) =>
  fns.forEach(
    fn =>
      (obj[fn] = function() {
        return fn.apply(obj);
      })
  );

var view = {
  label: 'docs',
  click: function() {
    console.log('clicked ' + this.label);
  }
};
bindAll(view, 'click');
jQuery(element).on('click', view.click); // Logs 'clicked docs' when clicked.
