Avoiding typical failure points

There are many scenarios where the normal implementation would fail. We are going to discuss these failure points and will see how to tackle them.

In this section, we will work with the following entities to tackle failure points:

• Selectors
• Scope of the variable
• Delay
• Element Exists
• Try / Catch
• toString method
