What are LTS releases of Node.js and why do they matter?
LTS stands for Long-Term Support. These are Node.js versions that receive active maintenance, security patches, and bug fixes for about 30 months — making them the recommended choice for production.
Stability — no breaking changes, safe for long-running production systems.
Security — regular patches for vulnerabilities.
Compatibility — most npm packages and frameworks target LTS versions.
Predictable upgrades — clear release timeline helps with planning.
Rule of thumb: Even-numbered versions (18, 20, 22) become LTS; odd-numbered ones (19, 21) don't.
This shows awareness of production best practices. Know the current LTS version and the release cadence.
Mentioning that you always use LTS in production demonstrates professional maturity.
