javascript | Object grouping

Question

I have an object. It looks like below:

[
  {
    \"name\":\"Display\",
    \"group\":\"Technical detals\",
    \"id\":\"60\",
    \"value\":\"4\"
  },
  {
           


        

Answer 1

Use reduce and filter.

lets say your initial array is assigned to data

data.reduce((acc, d) => {
    if (Object.keys(acc).includes(d.group)) return acc;

    acc[d.group] = data.filter(g => g.group === d.group); 
    return acc;
}, {})

this will give you something like

{
    "Technical detals" = [
    {
       'group'   = 'Technical detals',
       'name'    = 'Display',
       'id'      = '60',
       'value'   = '4'
    },
    {
       'group'   = 'Technical detals',
       'name'    = 'OS',
       'id'      = '37',
       'value'   = 'Apple iOS'
    }],
    "Manufacturer"   = [
    {
       'group'   = 'Manufacturer',
       'name'    = 'Manufacturer',
       'id'      = '58',
       'value'   = 'Apple'
    }]
}
