# ee.String.aside

<br />

Calls a function passing this object as the first argument, and returning itself. Convenient e.g. when debugging:

<br />

var c = ee.ImageCollection('foo').aside(print)

.filterDate('2001-01-01', '2002-01-01').aside(print, 'In 2001')

.filterBounds(geom).aside(print, 'In region')

.aside(Map.addLayer, {min: 0, max: 142}, 'Filtered')

.select('a', 'b');

Returns the same object, for chaining.

| Usage | Returns |
|---|---|
| `String.aside(func, var_args)` | ComputedObject |

| Argument | Type | Details |
|---|---|---|
| this: `computedobject` | ComputedObject | The ComputedObject instance. |
| `func` | Function | The function to call. |
| `var_args` | VarArgs\[Object\] | Any extra arguments to pass to the function. |

## Examples

### Code Editor (JavaScript)

```javascript
// aside with no var_args.
// a
ee.String('a').aside(print);

// foo
// bar
ee.String('foo').aside(print, 'bar');

// foo
// bar
//
// foo
print(ee.String('foo').aside(print, 'bar'));

// aside in the middle of a chain of calls.
// a
// b
//
// ac
print(ee.String('a').aside(print, 'b').cat('c'));

// aside with more than one var_args.
// a
// 1
// 2
ee.String('a').aside(print, 1, 2);

// Print a empty JSON string.
// ''
ee.String('').aside(print);
```
Python setup

See the [Python Environment](https://developers.google.com/earth-engine/guides/python_install) page for information on the Python API and using
`geemap` for interactive development.

```python
import ee
import geemap.core as geemap
```

### Colab (Python)

```python
def print_result(val, *params):
  """A print function to invoke with the aside method."""
  print(val.getInfo())
  for param in params:
    print(param)


# aside with no var_args.
# a
ee.String('a').aside(print_result)

# foo
# bar
ee.String('foo').aside(print_result, 'bar')

# foo
# bar
#
# foo
print(ee.String('foo').aside(print_result, 'bar').getInfo())

# aside in the middle of a chain of calls.
# a
# b
#
# ac
print(ee.String('a').aside(print_result, 'b').cat('c').getInfo())

# aside with more than one var_args.
# a
# 1
# 2
ee.String('a').aside(print_result, 1, 2)

# Print a empty JSON string.
# ''
ee.String('').aside(print_result)
```
