О чём код?
var underscore = require('./underscore.js'); var _executeBound = require('./_executeBound.js'); var restArguments = require('./restArguments.js'); // Partially apply a function by creating a version that has had some of its // arguments pre-filled, without changing its dynamic `this` context. `_` acts // as a placeholder by default, allowing any combination of arguments to be // pre-filled. Set `_.partial.placeholder` for a custom placeholder argument. var partial = restArguments(function(func, boundArgs) { var placeholder = partial.placeholder; var bound = function() { var position = 0, length = boundArgs.length; var args = Array(length); for (var i = 0; i < length; i++) { args[i] = boundArgs[i] === placeholder ? arguments[position++] : boundArgs[i]; } while (position < arguments.length) args.push(arguments[position++]); return _executeBound(func, bound, this, this, args); }; return bound; }); partial.placeholder = underscore; module.exports = partial;
