How to function call using 'this' inside forEach loop

Question

In the following object, I have a problem using the \'this\' reference:

function SampleObject(){
    this.addObject = function(object){...}
    ...
    // mo         


        

Answer 1

const array1 = [
  {name : "john", age: 20}, {name : "sarah", age: 70}
  ];

array1.forEach(element => this.print(element));

print = (data) =>
{
  console.log(data.name);
}
// expected output: "john"
// expected output: "sarah"

There is better way to do this

array.forEach(obj => this.functionName(params));
