如何将具有包含值、值的对象的数组转换为只有键、值的单个对象？

Question

So after drawing data for the database I ended up with something like

[
{name: "id", data_type: "integer"}
{name: "name", data_type: "char"}
{name: "active", data_type: "boolean"}
]

but what I want is:

{id: "integer" , name: "char" , active: "boolean" }

I tried a bunch of things but couldn't figured it out, any helps would be appreciated

This is my desperate attempt:

Object.entries(jsonData).map((type) => {
        return { ...objectList, [type[1].name]: type[1].data_type };
      }).reduce((objectList, object) => (
          ...objectList,
          object)
        )

Answer 1

Here is a simple approach:

 let arr = [ {name: "id", data_type: "integer"}, {name: "name", data_type: "char"}, {name: "active", data_type: "boolean"} ]; let map = {}; arr.forEach(e => map[e.name]=e.data_type); console.log(map);

If you want to use .reduce , try this:

 let arr = [ {name: "id", data_type: "integer"}, {name: "name", data_type: "char"}, {name: "active", data_type: "boolean"} ]; let map = arr.reduce(function(obj,item){ obj[item.name] = item.data_type; return obj; }, {}); console.log(map);

Answer 2

Here is a reduce

 const data = [ {name: "id", data_type: "integer"}, {name: "name", data_type: "char"}, {name: "active", data_type: "boolean"} ]; const arrayToObject = arr => arr.reduce((result, value) => { result[value.name] = value.data_type; return result; }, {}); console.log(arrayToObject(data));

Answer 3

another way is using Array.reduce()

const array = [
  { name: 'id', data_type: 'integer' },
  { name: 'name', data_type: 'char' },
  { name: 'active', data_type: 'boolean' },
];

const newObject = array.reduce((finalObj, obj) => {
  finalObj[obj.name] = obj.data_type;
  return finalObj;
}, {})

console.log(newObject)
