Tests:

Array.prototype.concat
var params = [ "hello", true, 7 ]; var other = [ 1, 2 ].concat(params);
spread operator
var params = [ "hello", true, 7 ] var other = [ 1, 2, ...params ]
Push
var params = [ "hello", true, 7 ]; var other = [ 1, 2 ].push(...params);
Object.assign
var params = [ "hello", true, 7 ]; var other = Object.assign([], params);
slice(0)
var params = [ "hello", true, 7 ]; var other = params.slice(0);
slice
var params = [ "hello", true, 7 ]; var other = params.slice();
Array.from
var params = [ "hello", true, 7 ]; var other = Array.from(params);
for loop
var params = [ "hello", true, 7 ]; var other = [] for (var i = params.length; i--; ) { other.unshift(params[i]) }
