Stuck on the bird watcher exercise

Programming JavaScript

I don’t know what’s wrong with my code, I attempt everything and couldn’t pass

// @ts-check
//
// The line above enables type checking for this file. Various IDEs interpret
// the @ts-check directive. It will give you helpful autocompletion when
// implementing this exercise.

/**
 * Calculates the total bird count.
 *
 * @param {number[]} birdsPerDay
 * @returns {number} total bird count
 */
export function totalBirdCount(birdsPerDay) {
  //starts with 0
  let count = 0;
  for (let i = 0; i < birdsPerDay.length; i++) {
    count += birdsPerDay[i]; //adds the number of birds per day to the count
  }
  return count; //-> return of the function
}
/**
 * Calculates the total number of birds seen in a specific week.
 *
 * @param {number[]} birdsPerDay
 * @param {number} week
 * @returns {number} birds counted in the given week
 */

export function birdsInWeek(birdsPerDay, week) {
  let sum = 0;
  //the same as the totalBirdCount function, but only for a specific week
  for (let i = 7 * (week - 1); i < 7 * week; i++) { // the week have 7 days, so we need to multiply the week number by 7 and -1 to get the first day of the week
    sum += birdsPerDay[i];
  }
  return sum;
}

/**
 * Fixes the counting mistake by increasing the bird count
 * by one for every second day.
 *
 * @param {number[]} birdsPerDay
 * @returns {number[]} corrected bird count data
 */
export function fixBirdCountLog(birdsPerDay) {
  // inicialize an empty array to store the correct data
  let everyTwoDays = [];
  //then Loop through the array and add 1 to every second day
  for (let i = 0; i < birdsPerDay.length; i++) {
    //if the index of the element is an odd number, increment by one
    if (i % 2 !== 0) {
      everyTwoDays.push(birdsPerDay[i] + 1);
    }
    //else just push the element to the new array
    else {
      everyTwoDays.push(birdsPerDay[i]);

      return everyTwoDays;
    }
  }
}

What happens when you run the tests? Is there an error message?

Hello! thank you for askin

SyntaxError: <solution>/bird-watcher.js: Identifier 'totalBirdCount' has already been declared. (61:16)

      59 | }

    > 61 | export function totalBirdCount(birdsPerDay) {

it’s really hard to know what’s happening :(

This suggests you’re defining the function on line 61. The code you shared shows the function defined on line 13.

Are you sharing your complete code? Is there additional code somewhere?
