Looking for a remote Dev team to build AIs that do more than research
Published: 2024-01-23 10:17:18

Hey DEV community, I'm new here but thought I'd give you all a shout out. I've been using OpenAI and Hugging Face since the launch last year. I got access to GPT-4 almost immediately nd have been playing around with it ever since. I have great ideas for it but need a team of more advanced developers to help me out with the cloud side of things. I got the great concepts, just need help with implementation.

I had taken a break from computers to raise a family and am a bit out of touch with all the new tech but my ideas are still 5 years ahead of their times :)

If anyone wants to be part of a small dev team that works on super cool Assistants, or Multi-Agent systems, I can give you more info when you pm me.

Have a great day everyone!

Why you should use ?? instead of ||

title: Why you should use ?? instead of ||
published: true

tags: 
canonical_url: https://hardnold.hashnode.dev/why-you-should-use-nullish-coalescing-instead-of-logical-or
---

We often see and write things like this:

```
function sayHey(name) {
  name = name || "Precious";
  console.log(`Hey ${name}`);
}

sayHey("Morty"); //Hey Morty
sayHey(); //Hey Precious
```

But did you know that the `??` operator, known as the **_nullish coalescing_**  **_operator_** , is often considered safer than the `||` operator (logical OR) in JavaScript for certain use cases because of how they handle falsy values?

Let me explain...

## Understanding Falsy Values

Let's first have a look at what is considered a falsy value in JavaScript. In JavaScript, the following values are considered falsy:

- `false`

- `0` (zero)

- `""` (empty string)

- `null`

- `undefined`

- `NaN` (Not a Number)

## How the logical OR (`||`) works

Now let's have a closer look at what the logical OR (`||`) operator actually does behind the scenes. `||` **returns the right-hand operand if the left-hand operand is falsy**. This is straightforward when you want to default to the right-hand operand **only if the left-hand one is** `null` **or** `undefined`. However, it can lead to unintended consequences with other falsy values like `0`, `""`, or `NaN`, which might be valid in your program logic.

Let's look at a simple example to better understand this:

```
const count = 0;
const defaultCount = count || 10; // defaultCount is 10, not 0
```

Here, `0` might be a valid value for **count** , but since `0` is considered falsy, `defaultCount` becomes `10` instead of `0`.

## How the nullish coalescing operator (`??`) works

The nullish coalescing operator (`??`) in contrast to the logical OR (`||`) returns the right-hand operand **only if the left-hand operand is** `null` **or** `undefined`. It does not react to other falsy values like `0`, `""`, or `NaN`. This makes `??` safer for certain use cases where you want to include these falsy values as valid inputs.

Let's look at our example from above again, but this time using `??`:

```
const count = 0;
const defaultCount = count ?? 10; // defaultCount is 0
```

Here, `defaultCount` correctly remains `0` because the nullish coalescing operator only checks for `null` or `undefined`, **not for any falsy value**.

## Conclusion

I hope this short article shed some light on the topic when to use `??` over `||`. The choice between `||` and `??` certainly depends on the specific requirements of your code, but next time you want to fallback to default values, I'd encourage you to spend one additional second to evaluate the right operator for your use case. In short:

- Use `||` when you want to use a default value for **any falsy value**.

- Use `??` when `0`, `""`, or `NaN` are meaningful values in your context and you only want to fall back to a **default for** `null` **or** `undefined`

5 lessons I learned as a GraphQL developer
Tags: graphql, webdev, softwaredevelopment, beginners
Published: 2024-01-23 09:32:02

GraphQL is a very powerful and versatile tool, but it's very easy to use it wrong.  

## 1. GraphQL is not REST
  
  GraphQL allows clients to request specific data in a single request, while REST uses a fixed set of endpoints with predefined data.  
  
  GraphQL queries are very different from REST endpoints. Expose your data to the client by creating generic queries, allowing the client to compose the request as they need. Decouple your API from the application.  
  
  **Avoid creating situation-specific queries.**  

## 2. Use Resolvers as functions
  
  **Resolvers can be functions; that's the real deal.**  
  
  Use them as functions; don't limit your data to what's in the database. Decouple the DB structure from the shape you want to expose to the client. Use resolvers to manipulate data and connect entities.  
  
  Make resolvers your strength; they are the reason why GraphQL is so powerful.  

## 3. Create Custom Scalars
  
  Create custom types in GraphQL, as it is a typed system.  
  
  You should create custom scalars for structures that don't fall into GraphQL standard scalar types. **Custom scalars can be used to validate input and output data, as well as to parse and serialize values in specific ways.**  
  
  Make your types safe and modular by using and reusing custom scalars.  

## 4. Cache data using Dataloaders
  
  The same data may be requested more than once in the same query.  
  
  Entities in GraphQL may be connected in different ways because GraphQL is a graph. Dataloaders ensure that the entity is only loaded the first time and cached every other time when this occurs.  
  
  Using dataloaders to cache data will greatly improve your performance.  

## 5. Decompose queries using Fragments
  
  Fragments are a way to make your GraphQL queries modular on the client.  
  
  Having one giant query on a single component on the client is not ideal. It is way better to split the query into multiple components where each component only requests the data it needs. Don't worry about multiple requests, several GraphQL frameworks will merge those queries automatically.  
  
  **Make queries modular using Fragments.**
