The code developed for the DELETE method in the lecture does not validate the request

pathname against wrong input. In this activity you need to update the code to account for the

following

Mapping the index arriving from the client$-$side to the correct index on the server$-$side.

i$.$e$.$ if the client sends the following curl request,

curl $-$X DELETE localhost:$8080/1$

the first item at index $0$ will be deleted rather than the second item at index $1.$

Accounting for a missing index. i$.$e$.$ if the client sends the following curl requests

curl $-$X DELETE localhost:$8080/$ or curl $-$X DELETE localhost:$8080$

the server replies with

Missing index for item to be deleted

Working with lists that could have indices that are more than one digit number. So far,

the code can handle indices between $0$ and $9.$ Adjust the code to handle indices from $1$

to $999.$

Accounting for an invalid value for an index. i$.$e$.$ if the client sends the following curl

request

curl $-$X DELETE localhost:$8080/$a

the server replies with

invalid item index

Hint: The JS function Number.isNaN$()$ static method determines whether the passed

value is the number value NaN, and returns false if the input is not of the Number type.

After completing the above modifications, upload the updated todoSrv. js to BB$.$
