Caching in JavaScript refers to the process of storing data in a temporary storage location 
so that it can be quickly accessed in the future. Caching can help to improve the performance
of web applications by reducing the number of requests made to the server and minimizing the
amount of data that needs to be downloaded.

There are several ways to implement caching in JavaScript. One common approach is to use the 
browser's built-in caching mechanism, which stores resources such as images, stylesheets,
and scripts in the browser's cache. This allows the browser to retrieve these resources
from the cache rather than downloading them from the server each time they are needed.

Another way to implement caching in JavaScript is to use a third-party library or framework,
such as Redis or Memcached. These tools provide a more advanced caching solution that 
allows developers to store and retrieve data quickly and efficiently.

In addition to these techniques, developers can also implement client-side caching using
browser storage mechanisms such as localStorage and sessionStorage. These storage
mechanisms allow developers to store data locally on the user's device, which can be
retrieved quickly and without requiring additional network requests.

Overall, caching is an important technique for improving the performance of JavaScript 
applications. By reducing the amount of data that needs to be downloaded and minimizing
the number of network requests, caching can help to create faster, more responsive web 
applications.

how to cache data in javascript

Comment

//For example when we have a function responsible for retrieving 
//and returning data we can use a strategy 
//called memoization to retrieve data from the cache 
//if it was already fetched before:

const axios = require('axios')

let fetchCount = 0

function memoize(fn) {
  const cache = {}

  return async function (key, ...args) {
    if (cache[key]) {
      return cache[key]
    }

    fetchCount++
    return (cache[key] = await fn(...args))
  }
}

const fetchDogs = memoize(function (page) {
  if (typeof page !== 'number') page = 1
  return axios
    .get(
      `https://dog.ceo/api/breeds/list/all
    `,
    )
    .then((response) => {
      return response.data.message
    })
    .catch((err) => {
      throw err
    })
})

async function start() {
  try {
    let dogs = await fetchDogs(`dogs_page_11`, 11)
    return dogs
  } catch (error) {
    const err = error instanceof Error ? error : new Error(String(error))
    console.error(`Error: ${err.message}`, err)
  }
}

const writeToCache = (cacheKey, data) => {
    localStorage.setItem(cacheKey, JSON.stringify(data))
}

const readFromCache = cacheKey => JSON.parse(localStorage.getItem(cacheKey)) || null

// For node use:
// export { readFromCache, writeToCache }
