no-extra-semi

This rule extends the base no-extra-semi rule. It adds support for class properties.

Note that this rule is classified as a "Suggestion" rule instead of a "Layout & Formatting" rule because adding extra semi-colons actually changes the AST of the program. With that said, modern TypeScript formatters will remove extra semi-colons automatically during the formatting process. Thus, if you use a formatter, then enabling this rule is probably unnecessary.
