Pass by Value

Burak Osman Yaldız — Sat, 07 May 2022 19:19:45 +0000

In this section We Will Discuss What Does Mean "Pass by Value"
We have 2 Type of Values

Pointer Wrapper Values

Map
Slices
Functions

Non-Pointer Values

Strings
Int
Floats
Booleans
Arrays
Stuctures

For non-pointers, we need to redefine separately, for example

Whenever we try to change it with a function parameter, a variable copy of a new parameter is created in the computer memory for that function, so it does not change even if we try to change the value of the variable in our next codes. due to scope range

package main

import "fmt"

func changevalue(i int) {
    i = 20
}

func main() {
    i := 5
    changevalue(i)

    fmt.Println("Value:", i) // Value: 5
}

If you ask how this is for the pointer wrapper value, they update the memory address directly instead of creating a copy for the variable.

package main

import "fmt"

func changevalue(y map[string]float64) {
    y["baklava"] = 15.5
}

func main() {

    menu := map[string]float64{
        "pie":       35.6,
        "ice cream": 20.4,
    }

    fmt.Println(menu) // map[ice cream:20.4 pie:35.6]
    changevalue(menu)
    fmt.Println(menu) // map[baklava:15.5 ice cream:20.4 pie:35.6]
}

How to Use "NuxtJS + Lanyard"

Burak Osman Yaldız — Fri, 22 Apr 2022 22:13:30 +0000

What is lanyard used for?

Lanyard is a service that makes it super easy to export your live Discord presence to an API endpoint and to a WebSocket for you to use wherever you want. This plugin creates a connection between Lanyard and your Nuxt app as a plugin and lets you access the $lanyard anywhere in your app!

🔧 Install

You'll need Node.js and an existing NuxtJS app to use this plugin

Download the module via NPM, Yarn or your package manager.
- For NPM: npm install @eggsydev/vue-lanyard
- For Yarn: yarn add @eggsydev/vue-lanyard

🚀 Setup for NuxtJS

Create *plugins * folder in root project
Create "Nuxtlanyard.js" in plugins folder (You don't need to use this name, it can be different name, but make a note of it. It will be used in nuxt.config.js)
Open "Nuxtlanyard.js" file to edit then write this code in your file

import Vue from "vue";
import VueLanyard from "@eggsydev/vue-lanyard";

Vue.use(VueLanyard);

Then you need to add your plugin to nuxt.config.js file

export default {
  plugins: [
    {
      src: "@/plugins/Nuxtlanyard.js",
      mode: "client",
    },
  ],
};

❤️ Examples

The current winnerose.live website is developed with lanyard's js side, but my website alysum is completely powered by nuxt.

async mounted() {
    const socket = await this.$lanyard({
      userId: '701896585604497490',
      socket: true,
    })
    // Set a listener for "message" event
    socket.addEventListener('message', ({ data }) => {
      const { d: status } = JSON.parse(data)
      this.profileurl = `https://cdn.discordapp.com/avatars/701896585604497490/${status.discord_user.avatar}.png?size=256`
      this.name = status.discord_user.username
