What is lambda?
Lambda, the 11th letter of the Greek alphabet (λ), is used as both a symbol and a concept in various fields of science, mathematics and computing. Although originally used as a symbol for wavelength in mathematical equations, developers and engineers now use lambda in computer programming and cloud computing.
As a symbol, lambda is used primarily in calculus and physics, most notably in the theories of general relativity and quantum mechanics. Programming languages such as Python and Java also use lambda, as well as machine learning (ML), cloud computing and event-driven applications.
