Install Node.js and Yarn

### 1. **Check if Node.js is Installed**
Run:

node -v

If it returns a version, then Node.js is installed. Otherwise, you need to install it.

### 2. **Install Node.js**
#### Using NodeSource:

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt-get install -y nodejs

(Replace `18.x` with the latest LTS version.)

#### Or Using nvm (Recommended):
If you prefer **nvm** (Node Version Manager), install it with:

curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.4/install.sh | bash
source ~/.bashrc

Then install Node.js:

nvm install --lts
nvm use --lts

### 3. **Verify Node.js and npm**
After installation, check:

node -v
npm -v

### 4. **Reinstall Yarn**
Once Node.js is installed, retry:

curl -o- -L https://yarnpkg.com/install.sh | bash

or install Yarn via npm:

npm install -g yarn

### **1. Remove Old Node.js (If Installed)**
Check if Node.js is installed:

node -v

If it's installed, remove it:

sudo apt remove nodejs -y
sudo apt autoremove -y

—

### **2. Install Node.js Using NodeSource (Latest Version)**
Run these commands:

curl -fsSL https://deb.nodesource.com/setup_current.x | sudo -E bash -
sudo apt install -y nodejs

After installation, verify:

node -v
npm -v

This will install the latest **Node.js** and **npm**.

### **3. (Optional) Install Node.js via NVM (Recommended for Version Management)**
If you want more control over Node.js versions, use **nvm (Node Version Manager)**:

#### **Install nvm:**

curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.4/install.sh | bash
source ~/.bashrc  # or source ~/.zshrc if using Zsh

#### **Install the Latest Node.js:**

nvm install node
nvm use node

#### **Check Version:**

node -v
npm -v

This method allows switching between Node.js versions easily.
