How can I convert Array of Objects into Array of Array of Array

Question

Hello Everyone I'm beginner in javascript I'm trying to convert from Array of objects into Array of array.I have tried some methods like Object.entries.But I didn't get the output what I expected.If anyone helps It will really helpful to me.Any kind of help would be appreciated.Thanks in advance....

My Input:

  var data=[
           {name:'TOYA',price:34},
           {name:'TOYB',price:24},
           {name:'TOYC',price:444},
           {name:'TOYD',price:54}
        ];


Expected Output:

   var data=[
           ['TOYA',34],
           ['TOYB',24],
           ['TOYC',444],
           ['TOYD',54]
        ];
     
 But I got:
 
[ [ '0', { name: 'TOYA', price: 34 } ],
  [ '1', { name: 'TOYB', price: 24 } ],
  [ '2', { name: 'TOYC', price: 444 } ],
  [ '3', { name: 'TOYD', price: 54 } ] ]
  
 using Object.entries(data);

`[name:'c++',price:34]` not valid javascript, so you **can't** get that with any code — Jaromanda X, Mar 28 '20 at 08:17
Would I be right in assuming that you mean `[["name", "c++"], ["price", 34]]` — Angshu31, Mar 28 '20 at 08:23
so, what you want is an Array of Array ... not an Array of Array of Array — Jaromanda X, Mar 28 '20 at 08:26

Use Object.values instead.

var data=[
     {name:'TOYA',price:34},
     {name:'TOYB',price:24},
     {name:'TOYC',price:444},
     {name:'TOYD',price:54}
];

var newdata = [];
for (let obj of data) {
  newdata.push(Object.values(obj));
}
console.log(newdata)

var data=[
           {name:'c++',price:34},
           {name:'java',price:24},
           {name:'python',price:444},
           {name:'php',price:54}
        ];


var result = Object.values(data).map(v => Object.values(v));
console.log(result)

You can use Object.values(arrayElement)

[{name:'c++',price:34},{name:'java',price:24},{name:'python',price:444},       {name:'php',price:54}].map((e)=>{return [Object.values(e)]})
