How to create dynamic variable using JavaScript

In JavaScript, dynamic variable names can be achieved by using 2 methods.

1). eval()

2). Window object

Examples:-

i want to create apple, banana and orange named variables or etc.

Using eval():-

        <script>

            let obj1 = ['apple', 'banana', 'orange'];

            for (let i = 0; i < obj1.length; i++) {

                //console.log(obj1[i])

                eval(`let ${obj1[i]} = ${i}`)

            }

            console.log(apple) //Output: 0

            console.log(banana) //Output: 1

            console.log(orange) //Output: 2

        </script>

Using Window object:-

            using this method we create a global variable.

        <script>

            let obj1 = ['apple', 'banana', 'orange'];

            for (let i = 0; i < obj1.length; i++) {

                //console.log(obj1[i])

                window[`${obj1[i]}`] = i

            }

            console.log(apple) //Output: 0

            console.log(banana) //Output: 1

            console.log(orange) //Output: 2

        </script>
