# cube.formulaEvaluation

Turns a cube's formula evaluation on or off.

```js
cube.formulaEvaluation(cubeName, shouldEvaluate)
cube.formulaEvaluation(cubeName)
```

Turning it off speeds up loading lots of data, because formulas aren't recalculated after every write. Remember to turn it back on afterwards.

## Parameters

| Parameter | Type | Description |
|---|---|---|
| `cubeName` | `string` | The cube's name. |
| `shouldEvaluate` | `boolean` | Optional. `true` to turn formula evaluation on, `false` to turn it off. Leave it out to check whether it's on. |

## Returns

Whether formula evaluation is on.

## Examples

```js
cube.formulaEvaluation("Profit and Loss", false); // Turn formula evaluation off
// Do some heavy data input...
cube.formulaEvaluation("Profit and Loss", true); // Turn it back on
```
