Tests:

concat
var params = [ "hello", true, 7 ]; var other = [ 1, 2 ].concat(params);
spread
var params = [ "hello", true, 7 ] var other = [ 1, 2, ...params ]
push
var params = [ "hello", true, 7 ]; params.push(1); params.push(2);
push spread
var params = [ "hello", true, 7 ]; params.push(...[1, 2]);
