  <p>Hello everyone!</p>
  
  <p>I'm a JavaScript developer. I know what is closure and how it works in JavaScript.</p>
  
  <p>But today I see a new noun "lambda". What is lambda? It appears to be relevant to closure in JavaScript. What's the difference between lambda and closure in JavaScript?</p>
  
  <p>Thank you!</p>
