[jmeriksson]

• Initializing the apiKey variable before the try/catch statement so it is accessible before when trying to run client.setApiKey(apiKey).

PR Summary

• Introduction of new variable 'apiKey' A new variable labelled 'apiKey' was created in the sendgrid.js file to manage the SendGrid API key.

• Assignment modification for 'apiKey' Changing the way we assign value to the 'apiKey'. Previously, it was done as a constant. Now, it is given value using the '=' operator which means it can change during the execution of the program.

• Modification to 'try-catch' block The try-catch block in the code has been modified. Now, inside the 'try' portion, the new 'apiKey' variable is assigned its respective value.

• Removal of 'catch' block We removed the catch block from the code. This usually handles errors, so we may have implemented a different error-handling method.

• Dynamic value assignment to 'apiKey' The 'apiKey' now gets its value by executing a certain command and utilizing the result after trimming extra spaces at its ending. This enables a more dynamic and real-time usage of the SendGrid API key.
