I have array of objects:
var x = [{a: 1,b:2}, {a:3,b:4}, {a: 5,b:6}];
I need to join array as follows:
1,2
3,4
5,6
I do not want to use from lodash or underscore
How can I get Join of array of objects ?

join() The join() method creates and returns a new string by concatenating all of the elements in an array (or an array-like object), separated by commas or a specified separator string. If the array has only one item, then that item will be returned without using the separator.
How it works: First, split the title string by the space into an array by using the split() string method. Second, concatenate all elements in the result array into a string by using the join() method. Third, convert the result string to lower case by using the toLowerCase() method.
The syntax for the map() method is as follows: arr. map(function(element, index, array){ }, this); The callback function() is called on each array element, and the map() method always passes the current element , the index of the current element, and the whole array object to it.
const x = [{a: 1,b:2}, {a:3,b:4}, {a: 5,b:6}];
console.log(x.map(Object.values));
Output:
[
[1,2],
[3,4],
[5,6]
]
Furthermore, if you really want a string (not clear from your question)
x
.map(o => Object.values(o).join(','))
.join('\n')
