I am currently working on Javascript and stuck with using for loop in objects

Question

[ { name: 'rajesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020' },
  { name: 'ramesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020' },
  { name: 'abhi', type: 'int', value: '5' }
 ]

I need to use for loop
I need output like this('rajesh':'07/21/2020,'ramesh':'07/21/2020','abhi': 5
Need to use JSON.stringify

Please add the details on what you have done so far here.

Your output is enclosed in parentheses ?

something like this maybe,

const data = [{
    name: 'rajesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020'
  },
  {
    name: 'ramesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020'
  },
  {
    name: 'abhi',
    type: 'int',
    value: '5'
  }
]

const convertedData = Object.fromEntries(data.map(({
  name,
  value
}) => [name, value]))

console.log(convertedData)
console.log(JSON.stringify(convertedData))

Steps Taken:

Convert data to touple (for getting it converted using Object.fromEntries)
Create Object from the touples
Convert to JSON

Try this

let arr = [ { name: 'rajesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020' },
  { name: 'ramesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020' },
  { name: 'abhi', type: 'int', value: '5' }
 ];


 let result = {};

 for(i= 0; i < arr.length; i++){
    result[arr[i].name] = arr[i].value;
 }

 console.log(result);
 console.log(JSON.stringify(result));

I believe this is what you're looking for:

const data = [
  {
    name: 'rajesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020'
  },
  {
    name: 'ramesh',
    type: 'varchar',
    length: 50,
    value: '07/21/2020'
  },
  {
    name: 'abhi',
    type: 'int',
    value: '5'
  }
]

const result = data.reduce((acc, curr) => {
  acc[curr.name] = curr.value
  return acc
}, {})

console.log(result, JSON.stringify(result))
