## spread + [link](./spread "Link to this entry.") + [source](https://github.com/lodash/lodash/blob/4.5.0正式版/lodash.src.js#L9125 "View in source.") + [npm](https://www.npmjs.com/package/lodash.spread "See the npm package.") ``` _.spread(func) ``` 創建一個調用 `func` 的函數。 `this` 綁定到這個函數上。 把參數作為數組傳入，類似于 [`Function#apply`](https://es5.github.io/#x15.3.4.3) **注意:** 這個方法基于 [spread operator](https://mdn.io/spread_operator) ### 參數 1. func (Function) 要應用的函數 ### 返回值 (Function) 返回新的函數 ### 示例 ``` var say = _.spread(function(who, what) { return who + ' says ' + what; }); say(['fred', 'hello']); // => 'fred says hello' var numbers = Promise.all([ Promise.resolve(40), Promise.resolve(36) ]); numbers.then(_.spread(function(x, y) { return x + y; })); // => 返回 76 ```
