This pull request introduces a new ESLint rule for optimizing repeated member access patterns in AssemblyScript code. The rule aims to improve performance, readability, and maintainability by suggesting the extraction of frequently accessed member chains into variables. Additionally, the pull request includes updates to documentation, plugin configuration, and test cases to support and validate the new rule.

New ESLint Rule: no-repeated-member-access

• Implementation of Rule:

  • Added the no-repeated-member-access rule in plugins/rules/memberAccess.ts. This rule identifies repeated member access patterns and suggests extracting them into variables for better performance and readability. It avoids warning for computed properties, array indices, or properties modified within the scope.
  • Added the rule to the ESLint plugin configuration in plugins/perfPlugin.ts.

• Documentation:

  • Created a detailed guide for the no-repeated-member-access rule in docs/rules/no-repeated-member-access.md. This includes rule details, options, examples (correct and incorrect usage), and related rules.

Testing Enhancements

• Test Suite for New Rule:
  • Added comprehensive test cases for the no-repeated-member-access rule in tests/rules/noRepeatedMemberAccess.test.ts. These cover valid scenarios, invalid scenarios, and edge cases to ensure the rule behaves as expected.
  • Updated the test suite configuration in tests/perfPlugin.test.ts to include the new rule's tests.
