如何更改 json 对象的所有属性名称

Question

I would like to change all the property names of a json object

const obj = {
  "country": "Value1",
  "area": "value2",
  "color_flag": "value3"
}

const newKeys = ["pays", "Superficie", "Couleur de drapeau"]

// I would like to have something like this : 

obj = {
  "pays": "Value1",
  "superficie": "Value2",
  "couleur_drapeau": "Value3"
}

Thanks in advance

Answer 1

You can clone your object using new keys, but you need to provide a map for your new keys like this:

const newKeys = {
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

Simply on the left put the original key, and on the right put the new one that in your case is the translation to french.

Then you need to loop over all keys of your original object and copy each value to the new object with the new key

const renamedObj = {}
for(let key in obj){
  const newKey = newKeys[key]
  renamedObj[newKey] = obj[key]
}

Final code should be like this:

const obj = {
  "country": "Value1",
  "area": "value2",
  "color_flag": "value3"
}

const newKeys = { // Keys map
  "country": "pays",
  "area": "superficie",
  "color_flag": "couleur_drapeau"
}

const renamedObj = {}
for(let key in obj){
  const newKey = newKeys[key]
  renamedObj[newKey] = obj[key]
}

renamedObj should look like this:

renamedObj = {
  "pays": "Value1",
  "superficie": "Value2",
  "couleur_drapeau": "Value3"
}
