improved code style by importing some use statements, substr replacing with strpos
helo, thanks for this PR. im gonna accept this PR if the build passes and you kindly can format the commit message to angular format (as are other commits before) : https://github.styleci.io/analyses/prOrAR
however since it is not feature or fix or significant refactor - i don't know if it should be #hacktoberfest-accepted though.
edit: since you are a first time contributor, as a courtesy i will mark it as #hacktoberfest-accepted :) (pls address the comment above though)
seems you didnt check https://github.styleci.io/analyses/prOrAR also might need to rebase commit msg for this one a7037d6
