invoked by a gesture from the user. Setting `userGesture` to `true` will remove
this limitation.
If the result of the executed code is a promise the callback result will be the
resolved value of the promise. We recommend that you use the returned Promise
to handle code that results in a Promise.
```js
contents.executeJavaScript('fetch("https://jsonplaceholder.typicode.com/users/1").then(resp => resp.json())', true)
.then((result) => {
console.log(result) // Will be the JSON object from the fetch call
})
```
**[Deprecated Soon](promisification.md)**
#### `contents.executeJavaScript(code[, userGesture])`
* `code` String
* `userGesture` Boolean (optional) - Default is `false`.
Returns `Promise<any>` - A promise that resolves with the result of the executed code
or is rejected if the result of the code is a rejected promise.
Evaluates `code` in page.
