If you’ve worked with JavaScript long enough, you’ve likely run into type-related issues. For instance, you might have accidentally converted a value from an integer to a string:
[Log] User’s cart value: "500100"” data-lang=”text/javascript”>
> console.log("User's cart value:", "500" + 100)
[Log] User's cart value: "500100"
A seemingly innocent error can become a problem if it resides in, say, your application’s billing code. And with JavaScript increasingly being used in critical services, such a scenario is likely to happen in real life. Luckily, database tools like Prisma deliver type safety in the database access layer for your JavaScript projects.
