how to extract array data only having multiple value in Javascript?

Question

i have this array data.

var arr = {key1:'progress',key2:'done',key3:['new','12'],key4:['checking','10']};

and i want extract array data,but it should only having multiple value data. so i want to get result array like this.

var result = {['new','12'],['checking','10']};

or

var result = {key3:['new','12'],key4:['checking','10']};

i googled for solving this but i couldnt get answer. is there way to do this?

Answer 1

You can filter the Object.values array based on whether a value is an array (using Array.isArray()) and checking its length:

var arr = {
  key1: 'progress',
  key2: 'done',
  key3: ['new', '12'],
  key4: ['checking', '10']
};

var result = Object.values(arr).filter(v => Array.isArray(v) && v.length > 1);
console.log(result);
