* First steps towards TypeScript conversion

* Convert xml.js->xml.ts

* Add compilation to build step

* Rewrite base.js in TypeScript (maybe shit, need to review own work once I'm done)

* Rewrite json.js -> json.ts and get tests passing (I'm honestly shocked they passed)

* array.js -> array.ts

* character.js -> character.ts

* css.js->css.ts

* sentence.js->sentence.ts

* word.js -> word.ts

* line.js -> line.ts

* index.js->index.ts

* Convert a couple more fiiles

* Convert params.ts

* string.js -> string.ts

* Partly convert patch-related files to TypeScript; more to do

* Type more stuff

* Begin converting line-endings.js. Interesting TypeScript bug along the way.

* Bump TypeScript

* Add link to bug report

* Finish converted line-endings.js to TypeScript

* Add missing overloads to support case where argument type isn't known statically

* reverse.js -> reverse.ts

* add todo

* Rewrite base.ts types (breaks everything for now)

* Per-diff-function options types. Still not compiling but close.

* Fix build

* Run 'yarn add @eslint/js typescript-eslint --save-dev' as suggested at https://typescript-eslint.io/getting-started

* Turn on recommended eslint rules as recommended by Getting Started guide at https://typescript-eslint.io/packages/typescript-eslint/#config

* Get linting of TypeScript working (now with the officially recommended rules)

* yarn lint --fix

* Tweak some indentation that eslint broke

* Fix a couple of linting errors

* Allow explicit 'any'

I'm using it and it's convenient. In some places like diffArrays where we allow arrays of arbitrary type, I don't even know how to NOT use it.

* Eliminate needless explicit respecification of rules that eslint.configs.recommended already enables

* Fix another eslint config bug

* Start using arrow functions and thereby resolve a https://typescript-eslint.io/rules/no-this-alias/ error

I wasn't using them before because I wasn't sure if our build process would turn them into normal functions for compatability with old JS environments; it turns out it does, so we're fine.

* Fix some linting errors about pointless escape sequences

* Fix more linting errors about pointless escape sequences

* Eliminate a util made redundant by Object.keys, and fix a linting error in the process

* Liberalise more rules

* Fix lint errors in parse.ts

* Fix lint errors in apply.ts

* Fix remaining linting errors

* Add missing newline at EOF

* Remove a couple of unused ts-expect-error directives. (My editor was showing errors but tsc doesn't.)

* create.js->create.ts

* Fix some linting errors

* Lint on build, like before

* Generate type declarations on build

* Migrate to using tsconfig.json instead of CLI args

* Start adding tsd tests... but actually maybe should use dtslint?

* Correctly mark a load of arguments as optional

* convert tests to tsd style

* Fix type test

* Fix some more type test things

* Undo some testing silliness

* aaaaaaaaaaargh

* Get most of the way to fixing type definitions based on #303 (comment). Doesn't compile yet.

* Fix another typing error

* Fix error-handling-related types in patch/apply

* Analyse errors I'm seeing in tests copied from DT & add TODOs

* Begin adding some docs

* Fix a load of test cases where the DT behaviour was just wrong

* Make diffArrays generic instead of using any

* Make DiffArraysOptions types generic

* Rename ParsedDiff -> StructuredPatch

* Export ApplyPatchOptions, ApplyPatchesOptions

* Make all methods public for backwards compat

* Fix remaining type error

* Fix ignoring of test-d

* Copy latest change from DT (DefinitelyTyped/DefinitelyTyped@2cfdb9f)

* Flesh out docs

* Resolve ignoreWhitespace dilemma

* nah

* durrrr

* failed fix attempt

* Get attw passing (hallelujah!)

* Enable "strict": true

* Fix a strict mode error

* Fix a strict mode error

* Fix more strict mode errors

* Silence a silly strict mode error

* Further placate strict mode

* Further placate strict mode

* Fix a legit type error that strict mode found

* Further placate strict mode

* Get TypeScript happy with create.ts

* Further placate strict mode

* Further placate strict mode

* Placate compiler about apply.ts

* Fix a load more strict mode errors

* Placate strict mode further

* Fix some more compilation errors

* Fix one more compilation error

* Fix remaining base.ts errors

* Fix line.ts

* Type a variable to remove a slew of compilation errors

* Add more types to resolve more errors

* Add even more types to resolve even more errors

* Fix remaining type errors. Huzzah!!!

* Address verbatimModuleSyntax guidance

* Remove obsolete comment

* Get @typescript-eslint/consistent-type-exports enabled

* Un-disable no-duplicate-type-constituents and let it autofix. I guess I was confused.

* Reenable another rule

* Remove no-longer-needed gitignore rule from earlier in this PR

* Remove an obsolete disabling of a rule from early in my eslint tinkering. No longer makes sense.

* Fix deps being wrongly declared as non-dev deps

* Bump new deps to latest

* Re-add support for imports from /lib/, maybe?

* Restore support for subpath imports in Node 12.19 and earlier (see #351 (comment)).

* Restore es5 support

* Improve docs; add more exports to obviate need to import stuff from lib/

* Fix rollup

* Improve docs; restore package.json top-level fields that maybe are useful for compatibility with something, somewhere

* Stop using babel with rollup.

Doesn't seem to really affect anything. Output in dist/diff.js is almost identical; just formatting changes and a handful of other things that look inconsequential.

* Remove unused dependency on Babel CLI

* Remove another unused dep

* Get karma working

* Remove apparently unneeded eslint ignore directives

* Fix misplaced bullet in release notes

* bah

* Begin the tedious work of copying and pasting the README documentation into the function comments, so it can show up in people's editors

* More copying and pasting. I should probably test this before moving on

* More copying and pasting of docs

* Finish pasting docs

* Revert temporary package name change

* Hackily resolve the Intl.Segmenter issue
