# This example demonstrates using the built-in console object.
# The Javascript run in this example is shown below.

# Load the JavaScript from a file.

# Run the JavaScript
# Results (not console output) go to result.
# Note: Eval returns the completion value of the script. This is generally the value of the last evaluated expression.
# In this case, the last evaluated expression is console.log which does not calculate a value. Therefore, it returns undefined.
$success = $js.Eval($sbScript,$result)
if ($success -eq $false) {
    $($sbScript.LastErrorText)
    exit
}

# We can look at the result, which is "undefined", which is normal and expected.
$($result.Emit())
# The result JSON is: {"type":"undefined","value":"undefined"}

# The console output is retrieved by calling ConsoleOutputSb
