What is the best way to change an array of strings into a single string in JavaScript?

I am working with a JavaScript array that contains strings arranged in a specific format:

arrayOfString = ['a', 'b,c', 'd,e', 'f'];

My goal is to transform this array into a new format like so:

myString = ["a", "b", "c", "d", "e", "f"];

Can anyone help me achieve this transformation?

Answer №1

Employ the combination of map, split, reduce, and concat:

const strings = ['a', 'b,c', 'd,e', 'f'];
const mergedString = strings.map(s => s.split(",")).reduce((acc, curr) => acc.concat(curr));
console.log(mergedString);

Description:

Utilize map to loop through the array, then separate each letter using split, proceed to use reduce and concat as established methods to flatten the resultant multi-dimensional array, eventually storing the output in myString.

Utilizing the power of join() and split()

Please note: The default separator for join() is a comma (,)

const arrayOfString = ['a', 'b,c', 'd,e', 'f']

const myString = arrayOfString.join().split(',')

console.log(myString)

To efficiently parse an array of strings containing commas, you can utilize the flatMap() method along with split()

let arrayOfString = ['a', 'b,c', 'd,e','f'];
let res = arrayOfString.flatMap(x => x.split(','))
console.log(res)

If your browser does not support flatMap(), you can achieve the same result by combining map(), concat(), and the spread operator. Simply pass the result of map() to concat() using the spread operator.

let arrayOfString = ['a', 'b,c', 'd,e','f'];
let res = [].concat(...arrayOfString.map(x => x.split(',')))
console.log(res)

Here's a clever way to utilize the spread operator, map function, and split method

let newArray = [];
let elements = ['apple', 'banana,pear', 'kiwi,mango', 'orange'];
elements.map(item => newArray = [...newArray,...item.split(",")])

console.log(newArray);
