“` #### 2. **Activate NVM** Reload your shell configuration: “`bash
source ~/.bashrc
“` Confirm NVM is installed: “`bash
nvm –version
“` #### 3. **Install Node.js with NVM** Install the latest Node.js version: “`bash
nvm install node
“` To install a specific version, replace `node` with the version number, e.g., `nvm install 18`. #### 4. **Set Default Node.js Version** Set a default Node.js version: “`bash
nvm use 18
nvm alias default 18
“` #### 5. **Verify Installation** Confirm Node.js and npm are installed: “`bash
node -v
npm -v
“` — ### Key Differences Between Snap and NVM | **Feature** | **Snap** | **NVM** | |———————–|—————————————|——————————–| | **Ease of Use** | Simple, system-wide installation. | Flexible, per-user management.| | **Version Control** | Limited to specific Snap versions. | Allows multiple versions. | | **Use Case** | Suitable for quick, single installs. | Ideal for developers managing multiple projects. | — ### Additional Tips – Use Snap for system-wide installations and NVM for development environments. – Keep your Node.js version updated for the latest features and security.
