check if a value is string in an object javascript

Question

I have this code. I need to write a validation for this object. if any of the property is empty or not a string console log an error or console log a message.

var obj = { "val1" : "test1", "val1" : "test1", "val1" : "test1", }

Here's an approach that might be easier to understand.

This code logs an error if one or more properties are not a string:

var obj = {
  "val1": "test1",
  "val2": 1,
  "val3": null
};

for (var property in obj) {
  if (typeof obj[property] !== 'string') {
    console.error(property + ' is not a string!');
  }
}
