To convert an array to a String in JavaScript, pass the array as an argument to the String() constructor. The String() constructor will return a string representation of the array.

If you want to convert an array to a string with a custom separator, you can use the Array.join() method. The join() method accepts an argument that specifies the character to use as a separator.

Let’s discuss these methods in detail below.

Convert An Array To A String In JavaScript Using String() Constructor

The String() constructor can be used to convert an array to a string. This is the most straightforward way to convert an array to a string.

Here’s an example:

var fruits = ['apple', 'banana', 'cherry'];

var fruitsString = String(fruits);

console.log(fruitsString); // 'apple,banana,cherry'

As you can see from the example above, the String() constructor returns a string representation of an array. The elements of the array are separated by commas.

Convert An Array To A String In JavaScript Using The Join() Method

The join() method can be used to convert an array to a string. This method accepts an argument that specifies the character to use as a separator.

Here’s an example:

var fruits = ['apple', 'banana', 'cherry'];

var fruitsString = fruits.join('-');

console.log(fruitsString); // 'apple-banana-cherry'

As you can see from the example above, the join() method returns a string representation of an array. The elements of the array are separated by the character specified as an argument to the join() method.

In the example above, we specified the character ‘-‘ as the separator. You can specify any character you want as the separator.

Here are some examples using other separators as well –

var fruits = ['apple', 'banana', 'cherry'];

var fruitsString = fruits.join('+');

console.log(fruitsString); // 'apple+banana+cherry'

var fruits = ['apple', 'banana', 'cherry'];

var fruitsString = fruits.join('*');

console.log(fruitsString); // 'apple*banana*cherry'

You can also omit the argument to the join() method. If you do that, the elements of the array will be separated by a comma.

Here’s an example:

var fruits = ['apple', 'banana', 'cherry'];

var fruitsString = fruits.join();

console.log(fruitsString); // 'apple,banana,cherry'

As you can see from the example above, the join() method returns a string representation of an array. The elements of the array are separated by commas.

Conclusion

In this article, we looked at how to convert an array to a string in JavaScript. We discussed two methods – the String() constructor and the join() method. We also saw how to specify a custom separator character using the join() method.
