Convert array to array of objects [duplicate]

Question

I have an array like this:

const categories = ["Action", "Comedy", "Thriller", "Drama"]

And I would like to convert it to this format:

const displayedCategories = [{"type": "Action", "isDisplayed": true},{"type": "Comedy", "isDisplayed": true},{"type": "Thriller", "isDisplayed": true},{"type": "Drama", "isDisplayed": true}]

Any advice ? :)

You can do so by using map:

const categories = ["Action", "Comedy", "Thriller", "Drama"];

const newCategories = categories.map(category => ({
  type: category,
  isDisplayed: true
}));

console.log(newCategories);

You can do so with the map method:

const displayedCategories = categories.map(function(category) {
   return { type: category, isDisplayed: true };
});

Maybe like This:

const categories = ["Action", "Comedy", "Thriller", "Drama"];
var out = [];
for(var key in categories){
  out.push({"type": categories[key], "isDisplayed": true});
}
console.log(out);

use array.prototype.map to convert the array into an object

categories = catergories.map(val => {
  var obj =  {
    type:val
    //more properties go here
  }
  return obj
}

const categories = ["Action", "Comedy", "Thriller", "Drama"]
const displayedCategories = categories.map(category =>  { return {"type": category, "isDisplayed": true} })
console.log('displayedCategories :', displayedCategories);
