javascript array - separate values and values of values by single quotes
Question
I have an array that looks like this:
var array = ["Rock Paper,Shoot,Dulce", "Once,Apple Mic,Chairs"]
I want to return the results like this:
'Rock Paper','Shoot','Dulce','Once','Apple Mic','Chairs'
This is what I have done so far:
includes = tagsI.map(tag => `'${tag}'`).join(',')
But this only separates by commas and single quotes the values.. not the values of the values as well.
How can I do this?
Thank you

Join the items of the array to a single string with commas. Split the string by the comma separators, map the items to the required format, and join again with commas.
const array = ["Rock Paper,Shoot,Dulce", "Once,Apple Mic,Chairs"] const result = array .join(',') .split(',') .map(tag => `'${tag}'`) .join(','); console.log(result);

split tag by comma and use another map
var tagsI = ["Rock Paper,Shoot,Dulce", "Once,Apple Mic,Chairs"] var result = tagsI.map(tag => tag.split(',').map(tag => `'${tag}'`)).join(','); console.log(result)

How about using reduce :
var array = ["Rock Paper,Shoot,Dulce", "Once,Apple Mic,Chairs"]; //V1 : compatible with all browsers var result = array.reduce((acc, elem, index, arr)=>{ var n_arr = elem.split(",").map(map_elem=> `'${map_elem}'`); n_arr.forEach(fe_elem => acc.push(fe_elem)); return acc; }, []).join(","); console.log(result); document.querySelector("#res1").innerHTML = result; //V2: compatible with some browsers var result2 = array.reduce((acc, elem, index, arr)=>{ var n_arr = elem.split(",").map(map_elem=>`'${map_elem}'`); acc.push(...n_arr); return acc; }, []).join(","); console.log(result2) document.querySelector("#res2").innerHTML = result2;
<body> <p id="res1"></p> <p id="res2"></p> </body>
The principle is the following :
We have an initial Array "array" in which we stored strings (["Rock Paper,Shoot,Dulce", "Once,Apple Mic,Chairs"])
For each string in the array:
- We split in an array the said string by ","
- We surround each element of this array by quotes
- We add each of these elements to the array that will be used as the result variable
- We created a string joining by ","
PS: If you want an array instead of a string, just remove the join(",")

You'll first need to split each element in the array.
var array = ["Rock Paper,Shoot,Dulce", "Once,Apple Mic,Chairs"];
var split = array.map(v => v.split(","));
var flattened = [].concat.apply([], split);
var str = flattened.join(",");
