Let’s say the following is our variable −
var message = 'This is the Class Demo';
Following is our object,
var object = new FirstClass(message)
The class FirstClass −
class FirstClass{ constructor( message){ this.message = message; } }
We will use eval() to call a JavaScript class object with variable. Following is the code −
Example
class FirstClass{ constructor( message){ this.message = message; } } var message = 'This is the Class Demo'; var object = new FirstClass(message) console.log(eval(object).message);
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo121.js.
Output
This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo121.js This is the Class Demo
