how to convert array to object of same key-CodePudding

I have a very simple thing I need to do, which is take an array/list of strings ['a.png', 'b.png', ...] and map it to an object with the same key "path" which looks like {path: 'a.png', path: 'b.png', ...}. How do I do this?

I've tried Object.assign to change the array to an object, which works, but then I can't figure out how to change all the keys to the same value. It is a long array so I don't want to do this manually. How do I assign all the keys in the object to "path"?

CodePudding user response：

You cannot have repeated keys in one object, instead you can create an array of objects to store all the paths there

const arr = ['a.png', 'b.png', 'c.png'];

const arrObj = arr.reduce((acc, prev) => {
  return [
    ...acc,
    {
      path: prev
    }
  ]
}, []);

console.log(arrObj);

you can use a reduce, in this way, I hope this solution will be of great help to you

const object = array.reduce((acc, item) => { acc[path] = item return acc }, {})
