you could put grades.length into a variable to avoid recalculating it every loop
| total += grades[i]; | ||
| } | ||
|

| let avg = total / grades.length; |

does avg end up as an integer or a float? If all the grades are whole numbers, it might be an integer, but you probably want to force it to do float math
| total += grades[i]; | ||
| } | ||

avg could also be const instead of a let
|
|
||
| let avg = total / grades.length; | ||
|
|
||
| return avg; |

instead of storing the average as a variable, you could return the calculation return value directly
| return avg; | |
| return total / grades.length; |
| total += grades[i]; | ||
| } | ||
|
|
||
| let avg = total / grades.length; |

| let avg = total / grades.length; | |
| let avg = total / parseFloat(grades.length); |

Can delete line 9 and just do:
| return avg; | |
| return total / grades.length; |
| total += grades[i]; | ||
| } | ||
|
|
||
| let avg = total / grades.length; |

Consider renaming avg to avgGrades to be clearer.
| return avg; | ||
| }; | ||
|
|
||
| export default calculateAverage; No newline at end of file |
| return avg; | ||
| }; | ||
|
|
||
| export default calculateAverage; No newline at end of file |
| for (let i = 0; i < grades.length; i++) { | ||
| total += grades[i]; | ||

This method will calculate the average of an array of grades.
