August 20, 2026 - A non-disjunctive ALL INNER JOIN condition is also unaffected, because there the condition is applied after the join instead. Where the expansion depends on one side only, move it into an ARRAY JOIN in a subquery before the join; a condition whose arrayJoin argument reads columns from both sides has to be restructured.

If you want to map objects to something (in this case a property). I think Array.prototype.map is what you're looking for if you want to code functionally.

If you want to support older browsers, that are not ES5 compliant you can shim it (there is a polyfill on the MDN page above). Another alternative would be to use underscorejs's pluck method:
var users = [
{name: "Joe", age: 22},
{name: "Kevin", age: 24},
{name: "Peter", age: 21}
];
var result = _.pluck(users,'name').join(",")

Well you can always override the toString method of your objects:
var arr = [
{name: "Joe", age: 22, toString: function(){return this.name;}},
{name: "Kevin", age: 24, toString: function(){return this.name;}},
{name: "Peter", age: 21, toString: function(){return this.name;}}
];
var result = arr.join(", ");
console.log(result);npm
