Splitting a 2-Dimensional Array

Question

I have this 2 dimensional array of tasks

const graph = [
    ['tie your shoes', 'put on your shoes'],
    ['put on your jacket', 'put on your shirt'],
    ['put on your shoes', 'put on your shorts'],
    ['put on your jacket', 'put on your shorts'],
    ['buy eggs from store', 'cook eggs'],
    ['heat up skillet', 'cook eggs']
]

I need to split up this graph into two separate arrays if the they have no association to each other. (ie, putting shoes on and cooking eggs have no association/relation within the graph)

Each array within the graph is an association of tasks. An association can be traced between two tasks if they can be traced back to a single common task - putting on your jacket can be traced back to putting on your socks

The result should look like this

const graph_1 = [
    ['tie your shoes', 'put on your shoes'],
    ['put on your jacket', 'put on your shirt'],
    ['put on your shoes', 'put on your shorts'],
    ['put on your jacket', 'put on your shorts']
]

const graph_2 = [
    ['buy eggs from store', 'cook eggs'],
    ['cook eggs', 'heat up skillet']
]

I'm not worried about sorting them at the moment - only concerned with splitting them up

Answer 1

You could use a combo of loops to check against an array that contains keywords.

 const graph = [ ['tie your shoes', 'put on your shoes'], ['put on your jacket', 'put on your shirt'], ['put on your shoes', 'put on your shorts'], ['put on your jacket', 'put on your shorts'], ['buy eggs from store', 'cook eggs'], ['heat up skillet', 'cook eggs'] ] // Keywords const clothes = ['shoes', 'jacket', 'shorts'] const foods = ['eggs', 'heat', 'skillet'] // Creating graph 1 const graph_1 = graph.filter(array => { return array.reduce((arr, str) => { clothes.forEach(item => { if (str.includes(item)) { arr.push(str) } }) return arr }, []).length }) // Creating graph 2 const graph_2 = graph.filter(array => { return array.reduce((arr, str) => { foods.forEach(item => { if (str.includes(item)) { arr.push(str) } }) return arr }, []).length }) console.log(graph_1) console.log(graph_2)
