A function in Typescript that returns an array of strings

I am experiencing an issue where my console statement is not displaying the length of the string array. Oddly enough, when I print 'list' within the for loop, it does show data.

public getText = (items: any) => {

  let list: string[] = [];

    for (let item of items) {
      list.push(item);
    }

  console.log('list ' + list);

  return list;
};

Furthermore, how can I go about calling this function?

Let's say I try to call the function using let items = ct.Text(titles);, but unfortunately nothing gets printed when I attempt to do so.

Answer №1

 function retrieveText(items:any){ 
  let list: string[] = [];
  for (let item of items) {
   list.push(item);
  }
  console.log('The length of the list is ' + list.length);

  return list.length;
 }

It's possible that length is not an attribute but a function, if so, you should use

 list.length()

To invoke the function:

 let size = retrieveText(items);
