 * An instance of a [`Client`] is a connection to a single

 *
 * The browser and node.js libraries both support the `websocket(url)`

 * instance over a WebSocket transport.
 *
 * In the browser, the `worker()` constructor creates a new Web Worker
 * `perspective_server::Server` and returns a [`Client`] connected to it.
 *
 * In node.js, a pre-instantied [`Client`] connected synhronously to a global
 * singleton `perspective_server::Server` is the default module export.
 *
 * # JavaScript Examples
 *
 * Create a Web Worker `perspective_server::Server` in the browser and return a
 * [`Client`] instance connected for it:
 *
 * ```javascript
 * import perspective from "@finos/perspective";
 * const client = await perspective.worker();
 * ```
 *
 * Create a WebSocket connection to a remote `perspective_server::Server`:
 *
 * ```javascript
 * import perspective from "@finos/perspective";
 * const client = await perspective.websocket("ws://locahost:8080/ws");

     * Creates a new [`Table`] from either a _schema_ or _data_.
     *
     * The [`Client::table`] factory function can be initialized with either a
     * _schema_ (see [`Table::schema`]), or data in one of these formats:
     *
     * - Apache Arrow
     * - CSV
     * - JSON row-oriented
     * - JSON column-oriented
     * - NDJSON
     *
     * When instantiated with _data_, the schema is inferred from this data.
     * While this is convenient, inferrence is sometimes imperfect e.g.
     * when the input is empty, null or ambiguous. For these cases,
     * [`Client::table`] can first be instantiated with a explicit schema.
     *
     * When instantiated with a _schema_, the resulting [`Table`] is empty but
     * with known column names and column types. When subsqeuently
     * populated with [`Table::update`], these columns will be _coerced_ to
     * the schema's type. This behavior can be useful when
     * [`Client::table`]'s column type inferences doesn't work.
     *
     * The resulting [`Table`] is _virtual_, and invoking its methods
     * dispatches events to the `perspective_server::Server` this
     * [`Client`] connects to, where the data is stored and all calculation
     * occurs.
     *
     * # Arguments
     *
     * - `arg` - Either _schema_ or initialization _data_.
     * - `options` - Optional configuration which provides one of:
     *     - `limit` - The max number of rows the resulting [`Table`] can
     *       store.
     *     - `index` - The column name to use as an _index_ column. If this
     *       `Table` is being instantiated by _data_, this column name must be
     *       present in the data.
     *     - `name` - The name of the table. This will be generated if it is
     *       not provided.
     *     - `format` - The explicit format of the input data, can be one of
     *       `"json"`, `"columns"`, `"csv"` or `"arrow"`. This overrides
     *       language-specific type dispatch behavior, which allows stringified
     *       and byte array alternative inputs.
     *
     * # JavaScript Examples
     *
     * Load a CSV from a `string`:
     *

     *
     * Load a CSV from a `UInt8Array` (the default for this type is Arrow)
     * using a format override:
     *
     * ```javascript
     * const enc = new TextEncoder();
     * const table = await client.table(enc.encode("x,y\n1,2\n3,4"), {
     *     format: "csv",

     * ```javascript
     * const table = await client.table(data, { index: "Row ID" });
     * ```
