In this article, we would like to show you how to pass array as function argument using JavaScript.

Quick solution:

xxxxxxxxxx
 
var array = ['a', 'b', 'c'];
​
function myFunction(arg1, arg2, arg3) {
    console.log(arg1, arg2, arg3);
}
​
myFunction(...array); // pass array as function argument

Auto running

Note:

The spread operator (...) was introduced in ES6.

Practical example

Edit

In this example, we present a solution that doesn't use the spread operator and works with older browsers.

xxxxxxxxxx
 
var array = ['a', 'b', 'c'];
​
function myFunction(arg1, arg2, arg3) {
    console.log(arg1, arg2, arg3);
}
​
myFunction.apply(this, array); // pass array as function argument
