Example:
```js
|eval(lambda: if("field" > threshold AND "field" != 0, 'true', 'false'))
|eval(lambda: if("field" > threshold AND "field" != 0, 'high', 'normal'))
.as('value')
```
The value of the field `value` in the above example will be the string `true` or `false`, depending on the condition passed as the first argument.
The value of the field `value` in the above example will be the string `high` or `normal`,
depending on the condition passed as the first argument.

```js
if(condition, true expression, false expression)
```
