JavaScript String Array to Object

Javascript string array to object

Super simple Array.prototype.map() job

names.map(name => ({ name }))

That is... map each entry (name) to an object with key "name" and value name.

var names = [    "Bob",    "Michael",    "Lanny"];
console.info(names.map(name => ({ name })))

Convert Array to Object

ECMAScript 6 introduces the easily polyfillable Object.assign:

The Object.assign() method is used to copy the values of all
enumerable own properties from one or more source objects to a target
object. It will return the target object.

Object.assign({}, ['a','b','c']); // {0:"a", 1:"b", 2:"c"}

The own length property of the array is not copied because it isn't enumerable.

Also, you can use ES8 spread syntax on objects to achieve the same result:

{ ...['a', 'b', 'c'] }

For custom keys you can use reduce:

['a', 'b', 'c'].reduce((a, v) => ({ ...a, [v]: v}), {}) 
// { a: "a", b: "b", c: "c" }

How to convert an array of type String to an array object in javascript

What you have here is a JSON string. You can parse it to get the object / array:

var array = JSON.parse(arrayString)

Edit: I see your JSON string has single quotes. You need to replace all of them with double quotes before parsing:

JSON.parse(arrayString.replace(/'/g, '"'))

You can do this using Array.map, which allows you to specify a function that returns a new item to replace in the array.

arr.map(function(o) {
   return {
      name: o,
   }
})
