JS log object why is showing [object Object]

Question

In JS, if I log a string to the console it is not showing properly ?

console.log(uniqueProducts); //
console.log("uniqueProducts:"+uniqueProducts);

result

[ { country: 'Russia', launches: 32 },
  { country: 'US', launches: 23 },
  { country: 'China', launches: 16 } ]
uniqueProducts:[object Object],[object Object],[object Object]
map

So why is [object Object] shown instead of the value? It is like it changes type with string appended?

Answer 1

You are concatenating an object to string

You can console a string and an object by separating it by comma(,)

you can console.log("uniqueProducts:", uniqueProducts );
