## castArray + [link](./castArray "Link to this entry.") + [source](https://github.com/lodash/lodash/blob/4.5.0正式版/lodash.src.js#L9262 "View in source.") + [npm](https://www.npmjs.com/package/lodash.castarray "See the npm package.") ``` _.castArray(value) ``` 如果 `value` 不是数组, 那么强制转为数组 ### 参数 1. value (\*) 要处理的值 ### 返回值 (Array) 返回转换后的数组 ### 示例 ``` _.castArray(1); // => [1] _.castArray({ 'a': 1 }); // => [{ 'a': 1 }] _.castArray('abc'); // => ['abc'] _.castArray(null); // => [null] _.castArray(undefined); // => [undefined] _.castArray(); // => [] var array = [1, 2, 3]; console.log(_.castArray(array) === array); // => true ```
