Visualizaçõesget array, separate comma separated values and then recreate array
I have the following array:
[
["Polymeric", "Vehicle Graphics (Basic)"],
["Cast", "Vehicle Graphics (Part Wrap), Vehicle Graphics (Full Wrap)"],
["Polymeric", "Vehicle Graphics (Part Wrap)"]
]
You'll notice that the 2nd lines of the array's second value has a value separated by a comma. I want to recreate the array like so.
[
["Polymeric", "Vehicle Graphics (Basic)"],
["Cast", "Vehicle Graphics (Part Wrap)"],
["Cast", "Vehicle Graphics (Full Wrap)"],
["Polymeric", "Vehicle Graphics (Part Wrap)"]
]
Here's what I have so far:
const media = [
["Polymeric", "Vehicle Graphics (Basic)"],
["Cast", "Vehicle Graphics (Part Wrap), Vehicle Graphics (Full Wrap)"],
["Polymeric", "Vehicle Graphics (Part Wrap)"]
];
var filteredArray = media.filter(function(r) {return r[1]})
filteredArray.forEach(function(value) {
var fgh = value.slice(1);
var cddd = [value.shift()]; // takes first part
var ttt = fgh.toString()
var str_array = ttt.split(', ');
const array3 = cddd.concat(fgh);
console.log(str_array);
});
I understand I need to use concat, split and then finally push it back but whatever I try I'm not getting the result I need so I need help and now I'm lost?

If you can ensure your nested arrays will always have two elements then it's quite simple:
const source = [
["Polymeric", "Vehicle Graphics (Basic)"],
["Cast", "Vehicle Graphics (Part Wrap), Vehicle Graphics (Full Wrap)"],
["Polymeric", "Vehicle Graphics (Part Wrap)"]
];
// Flat map instructs that
// the nested arrays we're going to return
// should be spread onto the root one
source.flatMap(([key, value]) => { // [key, value] de-structs the array passed as a parameter
// Here we're getting an array of all possible values;
// if there's no ", " then we get a single element,
// otherwise we get the whole collection of values
const values = value.split(', ')
// Now, for each of the individual values we create the key-value pairs
return values.map(singleValue => [key, singleValue])
})
Yields:
