"description":"<p>Javascript emerged in a specific context: the
fast-paced development of Netscape's browser. When he was hired at
Netscape, Brendan Eich was told that it would be \"Scheme for the
browser\", but he was later told to make it more like C and Java.
The first iteration of JS, created over a 10 day period, was a
super-flexible, but also highly flawed child of the internet
age.</p>",

"description":"The lambda calculus (also written as λ-calculus) is a
formal system in mathematical logic for expressing computation by
way of variable binding and substitution. It was first formulated by
Alonzo Church as a way to formalize mathematics through the notion
of functions, in contrast to the field of set theory. Although not
very successful in that respect, the lambda calculus found early
successes in the area of computability theory, such as a negative
answer to Hilbert's Entscheidungsproblem.<br><br>Because of the
importance of the notion of variable binding and substitution, there
is not just one system of lambda calculus. Historically, the most
important system was the untyped lambda calculus. In the untyped
lambda calculus, function application has no restrictions (so the
notion of the domain of a function is not built into the system). In
the Church–Turing Thesis, the untyped lambda calculus is claimed to
be capable of computing all effectively calculable functions. The
typed lambda calculus is a variety that restricts function
application, so that functions can only be applied if they are
capable of accepting the given input's \"type\" of data.",
