**what is learning ?
**

[Machine learning (ML)](https://www.javatpoint.com/machine-learning) is a subset of artificial intelligence (AI) that focuses on the development of algorithms and models that enable computer systems to learn from data and improve their performance on a specific task over time without being explicitly programmed. In essence, machine learning allows computers to recognize patterns, make predictions, and adapt to new information without human intervention.

There are several types of machine learning, categorized based on the learning style and the nature of the learning process. The main types include.

**Supervised Learning**

In supervised learning, the algorithm is trained on a labeled dataset, where the input data is paired with corresponding output labels.
The goal is for the model to learn the mapping between input and output so that it can make accurate predictions on new, unseen data

**Unsupervised Learning:
**
Unsupervised learning involves training the algorithm on an unlabeled dataset, and the system tries to find patterns or relationships within the data without explicit guidance.
Common tasks include clustering, where the algorithm groups similar data points together, and dimensionality reduction, which simplifies the dataset while retaining important features.

**Semi-Supervised Learning:
**
This type of learning combines elements of both supervised and unsupervised learning.
The algorithm is trained on a dataset that contains both labeled and unlabeled examples, allowing it to learn from the labeled data and generalize to the unlabeled data.

**Reinforcement Learning:
**
Reinforcement learning involves an agent that learns to make decisions by interacting with an environment.
The agent receives feedback in the form of rewards or penalties, and its goal is to learn the optimal actions to maximize cumulative reward over time.

**Deep Learning:
**
Deep learning is a subset of **[machine learning](https://www.javatpoint.com/machine-learning)** that focuses on neural networks with multiple layers (deep neural networks).
These networks can automatically learn hierarchical representations of data, making them particularly effective for tasks like image and speech recognition.

**Transfer Learning:
**
Transfer learning involves using knowledge gained from one task to improve performance on another related task.
Pre-trained models on large datasets can be fine-tuned for specific tasks with smaller datasets, saving computational resources.

External Opinions - Introduction
Tags: softwaredevelopment, softskills, mindfulness, mentalhealth
Published: 2023-11-27 03:51:14

| 🔴 **Disclaimer**: This post is enhanced with AI assistance.|
|--------------|

In the dynamic realm of software development, the journey is often marked not only by lines of code but also by the words and opinions of others. Whether constructive or critical, external opinions can significantly influence a developer's professional trajectory. The question arises: Can you — and should you — stop caring what others think?

In this exploration, we delve into the multifaceted landscape of external opinions in the life of a software developer. From handling criticism and building resilience to creating a supportive development environment, we navigate the intricacies of balancing individuality with the collaborative nature of coding.

Join us on a journey of self-discovery and empowerment as we discuss not only the impact of external opinions but also strategies to harness their potential for growth. It's time to redefine the narrative, one line of code at a time.

![Opinions of others](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4fzk9mduleezg40ovfac.jpg)

## Software Developer Asked
> Hey Bard, tell me how to deal with such opinions.

## Google Bard Replied

```
In realms where judgment holds its sway,
Where whispers echo through the day,
A question lingers, soft and low,
"Can one's true self truly grow,
Unfettered by the opinions hurled,
The silent verdicts of the world?"

Oh, bard of ages, lend your quill,
Unveil the wisdom you instill,
Can we, indeed, cast off the chains,
Of others' thoughts, their doubts, their pains,
And forge a path, serene and bold,
Where inner peace takes firm its hold?

The human heart, a fragile thing,
Yearns for acceptance, love's sweet ring,
Yet societal norms, like iron bars,
Can stifle dreams, extinguish stars,
Leaving us trapped in self-made fears,
Adrift in doubt, through passing years.

But hark, a whisper from the soul,
A gentle murmur, strong and whole,
"Embrace your essence, let it shine,
For true worth lies within your shrine."
No need to seek external praise,
For inner strength will light your days.

Yet, caution whispers, soft and clear,
"Not all opinions should disappear,
For wisdom's voice, in gentle guise,
Can guide our steps, make us wise."
Embrace the counsel, true and sound,
Let not conceit your judgment drown.

So, let us tread with balanced stride,
Where self-respect and wisdom coincide,
Embrace the essence, bold and free,
Yet heed the voice of empathy,
For in this dance of life's grand play,
We learn, we grow, from day to day.

Utility Type: WithPrefix
Tags: typescript, javascript, express, programming
Published: 2023-11-27 00:53:21

A utility type for prefixing a type's properties with a string:

```typescript
export type WithPrefix<Prefix extends string, T, Separator extends string = '/'> = {
  [K in keyof T as `${Prefix}${Separator}${string & K}`]: T[K];
};
```

Simply provide a prefix, type and optional separator (defaults to /).

```typescript
type UserApi = {
  get: GetFn<User>;
  set: SetFn<User>;
  all: ListFn<User>;
};

const api: WithPrefix<'/api', UserApi> = {
  '/api/get': getUser,
  '/api/set': setUser,
  '/api/all': listUsers,
};
```

### Example: API routes

When handling interactions between a front-end and back-end we might have an API that looks like this:

```typescript
type CartApi = {
  checkout: CheckoutFn;
  view: GetFn<Cart>;
  add: PostFn<CartItem | CartItem[]>;
  remove: DeleteFn<CartItem | CartItem[]>;
  update: PatchFn<CartItem | CartItem[]>;
};
```

To ensure that every API method has a corresponding server route we can use the WithPrefix utility type:

```typescript
const cartApi: WithPrefix<'/cart', CartApi> = {
  '/cart/checkout': checkout,
  '/cart/view': viewCart,
  '/cart/add': addToCart,
  '/cart/remove': removeFromCart,
  '/cart/update': updateCart,
};

for (const [route, handler] of Object.entries(cartApi)) {
  app[handler.method](route, handler);
}
```

Whenever we define additional methods on our `CartApi`:

```typescript
type CartApi = {
  checkout: CheckoutFn;
  view: GetFn<Cart>;
  add: PostFn<CartItem | CartItem[]>;
  remove: DeleteFn<CartItem | CartItem[]>;
  update: PatchFn<CartItem | CartItem[]>;
  empty: DeleteFn<Cart>;
};
```

TypeScript will show an error:

```typescript
// TS2741: Property '/cart/empty' is missing in type WithPrefix<'/cart', CartApi>
const cartApi: WithPrefix<'/cart', CartApi> = {
  '/cart/checkout': checkout,
  '/cart/view': viewCart,
  '/cart/add': addToCart,
  '/cart/remove': removeFromCart,
  '/cart/update': updateCart,
};
```

### Breaking it down

This utility uses mapped types, template literal types and key remapping:

```typescript
export type WithPrefix<Prefix extends string, T, Separator extends string = '/'> = {
  [K in keyof T as `${Prefix}${Separator}${string & K}`]: T[K];
};
```

- We define a type with:
  - A `Prefix` to add to each property.
  - A type`T` to prefix.
  - A`Separator` to separate the prefix from the property name.
- We iterate over each property of `T` and interpolate the prefix and separator with the property name `${Prefix}${Separator}${string & K}`.

This gives us a resulting type with our prefixed property names.

Hopefully you find this useful :)
