replace/replaceAll is not a function

I’m trying to use replace in order to remove some characters in a 2d array of strings, but I keep incountering an issue:

      dataArr[j,k] = dataArr[j,k].replaceAll(mCH, "");
                              ^

TypeError: dataArr[(j , k)].replaceAll is not a function

at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:77:12)
at node:internal/main/run_main_module:17:47

this is the part of my code using the function:

for (let j = 0; j < dataArr.length; j++)
{
  for (let k = 0; k < dataArr[j].length; k++)

  {
      dataArr[j][k] = dataArr[j][k].replaceAll('"', "");
      dataArr[j][k] = dataArr[j][k].replaceAll(":", "");
      dataArr[j][k] = dataArr[j][k].replaceAll("I", "");
      dataArr[j][k] = dataArr[j][k].replaceAll("L", "");
      dataArr[j][k] = dataArr[j][k].replaceAll("S", "");
      dataArr[j][k] = dataArr[j][k].replaceAll("}", "");
  }
}

Do I need to download anything? maybe there’s a problem with my code?

>Solution :

You can use the .replace function instead of replaceAll, if the later is not available.

"any string".replace(new RegExp("to replace", "g"), "new text")

This is by using new RegExp("text to replace", "g") as a string to search
