converting an array into an object javascript

Question

output: Array(5) [ "Samsung", "Iphone", "Nokia", "Xiomi", "Blackberry" ]

another output:  
Array(5) [ Object { id: "Samsung", label: "Samsung" },Object { id: "Iphone", label: "Iphone"},
Object { id: "Nokia", label: "Nokia"},Object { id: "Xiomi", label: "Xiomi"},Object { id: "Blackberry", label: "Blackberry"} ]

I want my 1st output to get converted into the type of 2nd output. I am trying to do this:

 mobilePhones = [
           {
           label: Object.keys(this.state.details.phones),
           id: Object.keys(this.state.details.phones,
           } 
         ]

but getting empty mobilePhones. my state is of type:

  state = {
        details:{
          phones: {},
        }
      } 

I am converting phones object into array so that I can iterate it over const mobilePhones and then again want it to convert to the object type.Its getting confusing for me. Can anyone please help me with this.

Answer 1

 const output = [ "Samsung", "Iphone", "Nokia", "Xiomi", "Blackberry" ] const brands = output.map(brand => ({id: brand, label: brand})); console.log(brands);

Answer 2

Use array.map for this.

 let array = [ "Samsung", "Iphone", "Nokia", "Xiomi", "Blackberry" ] let result = array.map( el => { return {id: el, label: el}}) console.log(result);

Answer 3

You can use map function to get the result of second array.

const type2 = type1.map((item) => {
  return {
    id: item,
    label: item
  }
});
