Let's say the data we get from an API looks like this “Airbrake-is-awesome,” and output should be a string “Airbrake is awesome.”

Let's continue this demostration and use the same example. This is how the computer program reads the split(): string.split(delimiter, limit)

What just happened here? Why did the A.split(“ “) turn our original string into an array? Let A = “Airbrake Error Monitoring and Debugger” When using a split() within a string, the substring returns as an array. The split() method is one of the most popular ways JavaScript developers convert their strings into arrays. The split() method is the most popular way to do this. You might need to convert those strings into an array in some cases. A string stores characters, while an array creates list-like objects due to its ability to hold more than one value. Or, perhaps, you have a list of strings that you want to call on as an array because, from a data point of view, it makes more sense.Ĭonverting Strings to Arrays in JavaScriptĪs you can see, strings and arrays serve two different purposes. For this purpose, we will split the string data by using a delimiter (which we'll go over in the next section) for every occurrence of “-” to get the final output “Airbrake is awesome.” Perhaps the API might contain a specific character for ‘Airbrake-is-awesome’ that is not required in the final output. By changing a string into an array, it allows us to take control of certain data points.įor example, maybe we have incorrectly formatted data coming from the API. When working with Data, there are times when we're in control and when we're not. You’ll receive the following list when you run this script:Īirbrake, Error Monitoring, Debugging. It’s perfect when you need to create and store lists.Ĭonst A =

If you already know what an array is and you’re comfortable working with arrays, please proceed to the next section, where we’ll go over how to convert strings to arrays.įor those of you who might need a refresher on arrays, here’s a simple definition:Īn array in JavaScript uses a single variable to store several elements. Next, we’ll provide a quick refresher on what an array is in JavaScript. Or you can put the exact same string in double-quotes:

What you need to know is that a JavaScript string stores a series of characters within quotes.

So, we won’t spend too much time on this particular topic. Whether you’re just starting in JavaScript or you’re an expert, you’re most likely familiar with JavaScript strings. With these foundations in mind, you should be able to understand better how to convert a string into an array without causing an error. The act of changing the string is simple, but if not done properly, you might see errors or even latent errors.īefore diving into errors commonly associated with changing a string into an array, it might be helpful to go into how to create strings and arrays in JavaScript. Converting a string into an array in JavaScript is tricky.
