Typescript types are not recognized, jsdoc comments confused

[technobuddha]

The very first typescript I attempted to generate jsdoc comments for:

/**

• @param {} {data
• @param {{data:T[]} columns}
• @param {ColumnSpecifications}} columns?
• @returns Shape
  */
  function analyze<T = unknown>({data, columns}: {data: T[], columns?: ColumnSpecifications}): {types: Record<string, ColumnType>, shape: Shape} {

The arguments are incorrect with the types and don't have correct syntax (The number of open/closed braces don't match). The return type is also incorrect.
