All of them work perfectly fine and produce the same results. If all you want to do is convert a string into an array of individual characters, you can use any of the above methods. In this article, we looked at 4 different ways to convert a string into an array in JavaScript.

You should always use the om() or a spread operator for strings containing emojis: const str = 'Pizza 🍕' const chars = Ĭonsole. The String.split() method attempted to split up the emoji into individual characters. This is because the emojis are unicode characters made up of two characters. split ( '' ) Īs you can see above, the 🍕 emoji is converted into two unknown characters. Let us look at the following example: const str = 'Pizza 🍕' const chars = str. If the string you are trying to split contains emojis, then String.split() and Object.assign() might not be the best choice. This method means that it will copy all string properties to the new array. This method copies 'all enumerable own properties'. assign (, str ) īe careful while using Object.assign() to split a string into an array. You can also use the Object.assign() method to convert a string into a characters array, as shown below: const str = 'JavaScript' const chars = Object. ) is another modern way to convert a string into an array in ES6: const str = '🍑🍓🍉🍇🍒' const fruits = Ĭonsole. However, you can use a polyfill to push the browser support way back to IE6. The om() is part of ES6 and only works in modern browsers. If you pass in a string to om(), it will be converted to a characters array: const str = '🍑🍓🍉🍇🍒' const fruits = Array. The om() method creates a new Array instance from a given array or iterable object. The String.split() method works in all modern browsers and back to at least IE 6. For example, let us limit our fruits list to only include the first two items: const str = 'Apple,Orange,Mango,Cherry' const fruits = str. To limit the number of items in the array, you can pass in a second parameter to specify the number of splits. If an empty string ( '') is used as a separator, the string is split between each character: const str = 'apple' const chars = str. You can split the string by almost anything: dashes, underscores, or even empty spaces: const str = 'Apple Orange Mango Cherry' const fruits = str.

You can also optionally pass in an integer as a second parameter to specify the number of splits.įor a comma-separated string, you can convert it into an array like this: const str = 'Apple,Orange,Mango,Cherry' const fruits = str.

It splits the string every time it matches against the given separator. The String.split() method converts a string into an array of substrings using a separator and returns a new array. Note: If you need to convert an array to a string in JavaScript, read this article.

The Object.assign() method also takes the string as input and returns a character array.

) from ES6 converts the string into a characters array.

The om() method accepts a string as input and returns a character array.

The String.split() method uses a separator as a delimiter to split the string and returns an array.
