Question

How do I display the content of a JavaScript object in a string format like when we alert a variable?

The same formatted way I want to display an object.

Answer 1

If you want to print the object for debugging purposes, use the code:

var obj = {
  prop1: 'prop1Value',
  prop2: 'prop2Value',
  child: {
    childProp1: 'childProp1Value',
  },
}
console.log(obj)

will display:

Note: you must only log the object. For example, this won’t work:

console.log('My object : ' + obj)

Note ‘: You can also use a comma in the log method, then the first line of the output will be the string and after that, the object will be rendered:

console.log('My object: ', obj);
