javascript alert prints Object Object

this is my code which prints below output on the alert.

alert(JSON.stringify( args.errors,null,4));

this is the output.

{
    "Weight":{
        "errors":[
            "Hello My name is John"
        ]
    }

If args is your object, you could simply alert args.Weight.errors and, in case there is more than one error, add join(', ') to list them separated by ,.

let args = {
  "Weight": {
    "errors": [
      "Hello My name is John"
    ]
  }
};
alert(args.Weight.errors.join(', '));

You can use args.Weight.errors.join(', ') to alert the errors.

In case if there is only one error, it will be shown. Otherwise, all the errors will be separated by ,.

I am assuming you are having

let args = {
    "Weight":{
        "errors":[
            "Hello My name is John"
        ]
    }
};

alert(args.Weight.errors.join(', '));

It should work.

I assume the output you mentioned is the error data and you want to display the errors from the that.

const data = {
    Weight: {
      errors: ["Hello My name is John"]
    }
};

To alert the users with above data you can use

alert(data.Weight.errors[0])
