Update all objects property value in array-CodePudding

I have array of objects, that I get by array.filter. Now I want to make .map() function on this array and change specific object property in all objects in this array. Something like this

.map(task => task.description = task.description.replace(...);

But this gives me array of strings, not array of objects with this updated property. How to make this returning whole objects with just description updated?

CodePudding user response：

Avoid to use "=" after arrow function if you do not explicite the return value

Try this :

const test = tasks.map(task => {
  task.description = task.description.replace(...)
  return task
});
console.log(test)

remember that, once you've .filter followed by .map, better to use .reduce() otherwise you'll loop twice on the same array.
