JavaScript Array to String

You can convert a JavaScript array to a string using the built-in toString method.

When you use this method, it will return a string of your array's elements separated by commas.

JAVASCRIPT
const numbers = [1, 2, 3, 4, 5];
const numbersString = numbers.toString();

console.log(numbersString);

// "1,2,3,4,5"

If you want to convert an array of objects to a string of their values, you can first convert the object to JSON, then log it to the console.

JAVASCRIPT
const obj = [
    {
        name: "New York",
        country: "USA"
    },
    {
        name: "Paris",
        country: "France"
    },
    {
        name: "London",
        country: "UK"
    }
];

const objString = JSON.stringify(obj);

console.log(objString);

// [{"name":"New York","country":"USA"},{"name":"Paris","country":"France"},{"name":"London","country":"UK"}]

Array to String without Commas

When you want to convert an array to a string without commas, you can use the join method. This method is called on an array and joins each element together with a specified separator.

JAVASCRIPT
const numbers = [1, 2, 3, 4, 5];

numbers.join(); // "1,2,3,4,5"
numbers.join("-"); // "1-2-3-4-5"
numbers.join(" "); // "1 2 3 4 5"

Now you know how to convert a JavaScript array to a string, with or without commas!
