This is the summary of Lightning Locker Service in Salesforce.
If you are not aware of Lightning Locker Service then I strongly recommend, Learn Lightning Locker Service here.
What Locker Service does is prohibit certain types of behaviors, such as trying to peek into the DOM of a component outside your own namespace.
For example, Locker Service disallows the following code example:
<lightning:button aura:id="button1" label="My Button" />
var element = component.find("button1").getElement();
You can’t use component.find("button1").getElement() to access the DOM element created by lightning:button.
Locker Service doesn’t allow a Lightning component to access the DOM for lightning:button because the button is in the lightning namespace and Lightning Component is in the namespace.
