Convert array object to value of strings

I have an array of objects structured like this:

[{ a: '1', b : '2'}, {a : '3', b : '4'}]

For the purpose of preparing data for insertion into database, I need a string of object values like this:

('1', '2'),('3', '4')

With the same ordering of values.. apart from the naive way of iterating through each object in array and constructing a string, is there a better much easier way of doing this?

For on line lovers.

var arr = [{ a: '1', b : '2'}, {a : '3', b : '4'}];

var result = arr.reduce(function(result, item, i){
    return result + "('" + item.a + "', '" +  item.b + "')" + i===arr.length-1?'': ',';    
}, '');

Try following

var arr = [{ a: '1', b : '2'}, {a : '3', b : '4'}];
    
var result = arr.map(function(item){
    return "('" + item.a + "', '" +  item.b + "')";    
});
    
console.log(result);
console.log(result.join());
