Question

I am a rookie at javascript, I have just gone through few of array methods and wanted to play with it, I’m stuck at this code that I’ve written:

function customFindProperty(arrayToFind,requiredItem){

  var elementIndex = 0;

  function isRequiredItem(item){
    elementIndex++;
    return item==requiredItem;
  }

  elementFound = arrayToFind.some(isRequiredItem);

  if(elementFound){
    return arrayToFind(elementIndex);
  } else{
    alert("Element Not Found");
    return undefined;
  }
}
var myElement = customFindProperty([1,2,3,4,5],3);

This gives me the error TypeError: Object is not a function I think I’m not even missing any semicolons.

Additional Info:
typeof customFindProperty returns “function”

Note
Don’t know how to close this question I found the answer it’s a simple typing mistake I was trying to return arrayToFind(elementIndex) instead of arrayToFind[elementIndex]

Answer 1

You are using parentheses instead of square brackets for your array access. arrayToFind(elementIndex); should be arrayToFind[elementIndex];.
