# wx.onMemoryWarning(function callback)

Listens on the insufficient memory alarm event.

In most cases, it is only an alarm. Developers can reclaim some unnecessary resources after receiving the alarm to free up memory space.

# Parameters

The callback function for the insufficient memory alarm event.

# Parameters

# Object res

  console.log('onMemoryWarningReceive')
})
