JavaScript String to Array and add boolean

I need to add true after splitting string into array:

var str = "California,Nevada";
var array = value.split(',');
this.setState({ value: array });
console.log(this.state.value)
// result is ["California", "Nevada"]

I needed result like this:

{California: true, Nevada: true}

You can use array#map function along with split to create the new object

var newObj = {};
var str = "California,Nevada".split(',').map(function(item) {
  newObj[item] = true;
});
console.log(newObj)

Assuming you want to split str and not value in the second line, you can do something like below.

var str = "California,Nevada";
var array = str.split(',');

// I think you need to use this.state instead of state
var state = {}; 
array.forEach(item => state[item]=true);
console.log(state)

So what you wanna do is creating a new object and then iterate over the splitted input like this:

const input = "California,Nevada";
const output = {};
input.split(',').forEach( item => output[ item ] = true );
console.log( output );

You could try this:

var str = "California,Nevada";
var result = {};
str.split(',').forEach(function(e){
  result[e] = true;
});

console.log(result);
