What is the difference between a 'closure' and a 'lambda'?

Hello everyone!

I'm a JavaScript developer. I know what is closure and how it works in JavaScript.

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?

Thank you!

Refer to Wikipedia:
