N-grams of longer arrays?

[sgpascoe]

Is it possible to get the bigrams of: [alpha bravo bravo, charlie delta, alpha bravo]

Ideally I'd like a return of

2 alpha bravo
1 bravo bravo
1 charlie delta
0 bravo charlie
0 delta alpha

Perhaps my inputs are wrong, but it seems to be crossing the boundaries to return

2 alpha bravo
1 bravo bravo
1 charlie delta
1 bravo charlie
1 delta alpha

Sorry I've got it!

        var ngramtester = ['alpha bravo bravo', 'charlie delta', 'alpha bravo']
        var newgramarray = [];
        for (var i = 0; i < ngramtester.length; i++) {newgramarray.push(await bigram(ngramtester[i].split(' ')))

I don’t understand the question.
You’re making some mistakes with JavaScript btw. await should not be needed for example.
You’re also wrapping bigrams in a way that should not be needed?
