I think the question is pretty straightforward, but still:

I have an object obj. How do I create array from this single object? Is it just [obj]

• 2 That's right. Just put it into array literal and you get an array of single element. – DecPK Commented Sep 8, 2021 at 10:38
• Yes. There are few other ways too but yours is already the most concise. – Tushar Shahi Commented Sep 8, 2021 at 10:40
• 1 Just a tip for next time, I wouldn't pose this questions as React Native based, this is purely a JavaScript question. – Dan Zuzevich Commented Sep 8, 2021 at 10:57

You have several ways to do this:

1. init an array and push obj inside:

   let array = [];
   array.push(obj);
   

2. init an array with obj:

   let array = [obj];
   

3. use fill function:

   let array = new Array(1).fill(obj);
   

You can try this,

const array = [];

array.push(obj);

Output:

array = [obj]
