Cannot import functions from another file in Typescript

Question

In my typescript file, I have these functions:

export {convertToArray, getColumn}


function convertToArray(fileName: string): StringTable {
  ...
}

function getColumn(columnName: string, table: StringTable): string[] {
  ...
}

And I'm trying to import them in another Typescript file:

import {convertToArray, getColumn} from './csv-reader'

But now it's telling me that my functions are declared locally but never exported.

That's because you exported them before defining them. Try with:

export function convertToArray(fileName: string): StringTable {
  ...
}

export function getColumn(columnName: string, table: StringTable): string[] {
  ...
}
