How can I scale all the objects in the array at the same time?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DrawLinesAnimated : MonoBehaviour
{
    public Transform[] objectsToScale;

    private void Start()
    {
        for (int i = 0; i < objectsToScale.Length; i++)
        {
            StartCoroutine(scaleOverTime(objectsToScale[i], new Vector3(2, objectsToScale[i].transform.localScale.y, objectsToScale[i].transform.localScale.z), 2));
        }
    }

    bool isScaling = false;

    IEnumerator scaleOverTime(Transform objectToScale, Vector3 toScale, float duration)
    {
        //Make sure there is only one instance of this function running
        if (isScaling)
        {
            yield break; ///exit if this is still running
        }
        isScaling = true;

        float counter = 0;

        //Get the current scale of the object to be moved
        Vector3 startScaleSize = objectToScale.localScale;

        while (counter < duration)
        {
            counter += Time.deltaTime;
            objectToScale.localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);

            yield return null;
        }

        isScaling = false;
    }
}

I tried using a loop :

for (int i = 0; i < objectsToScale.Length; i++)

But it's scaling only the first object in the array.

Do it all in the coroutine.. (unchecked code, may have odd errors but..)

This will run through all items in the array a bit like you tried.. If you want in parallell you'd need to funk it up a little.

Enumerator scaleOverTime(float ScaleSize, float duration)
{
    if (isScaling) yield return break;
    isScaling = true;
    for (int i = 0; i < objectsToScale.Length; i++)
    {

        float counter = 0;

        //Get the current scale of the object to be moved
        Vector3 startScaleSize = objectToScale[i].localScale;
        Vector3 toScale = startScale*ScaleSize;
        while (counter < duration)
        {
            counter += Time.deltaTime;
            objectToScale[i].localScale = Vector3.Lerp(startScaleSize, toScale, counter / duration);

            yield return null;
        }

     }
    isScaling = false;
}
