Javascript array contains/includes sub array

Question

I need to check if an array contains another array. The order of the subarray is important but the actual offset it not important. It looks something like this:

var master = [12, 44, 22, 66, 222, 777, 22, 22, 22, 6, 77, 3]; 

var sub = [777, 22, 22]; 

So I want to know if master contains sub something like:

if(master.arrayContains(sub) > -1){
    //Do awesome stuff
}

So how can this be done in an elegant/efficient way?

Answer 1

var master = [12, 44, 22, 66, 222, 777, 22, 22, 22, 6, 77, 3]; 

var sub = [777, 22, 22]; 

console.log(master.join(',').includes(sub.join(',')))

//true

You can do this by simple console.log(master.join(',').includes(sub.join(','))) this line of code using include method
