How to inline combine arrays in JavaScript?

Question

Given two arrays, how to to pass a combination of both to a function, preferably with inline syntax?

var current = [1.01, 3.01, 2.42, 4.31];
var preview = [0.89, 3.15];

/*
 * pass both combined to a function, this is fictional syntax.
 * display(current + preview);
 */

What I mean by inline syntax to create an temporary array which gets passed. I don't want one of my arrays to be modified.

您可以使用concat来创建一个包含两个值的新数组：

display(current.concat(preview));
