How to fill form with JSON?

Question

I get ajax response as JSON and need to fill a form with it. How to do that in jQuery or something else ? Is something better than using $(json).each() ?

Came here searching for a solution that didn't involve jQuery or a brunch of DOM scaning, but didn't find one... so here is my vanilla js solution brought to you other guys that probably ditched jQuery long ago.

const data = { 
  "id" : 12,
  "name": "Jack",
  "description": "Description",
  "nonExisting": "works too"
}

const { elements } = document.querySelector('form')

for (const [ key, value ] of Object.entries(data) ) {
  const field = elements.namedItem(key)
  field && (field.value = value)
}
