Syntax error Add object to array in JavaScript if name does not already exist?

Add object to array in JavaScript if name does not already exist?

For this, use push() along with forEach(). Following is the code −

Example

var details = [{name:"John"},{name:"David"}]
var addObject = ["Mike","Sam"];
addObject.forEach( obj1 => {
   if(!details.find( obj2 => obj2===obj1 ))
      details.push({name:obj1})
})
console.log(details);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo165.js.

Output

This will produce the following output −

PS C:\Users\Amit\javascript-code> node demo165.js
[
   { name: 'John' },
   { name: 'David' },
   { name: 'Mike' },
   { name: 'Sam' }
]
