What is a lambda expression, and when should I use one? Here is another really good reference which explains very well what are lambda expressions in C++: Microsoft com: Lambda expressions in C++ I especially like how well it explains the parts of a lambda expression, in particular: the capture clause, parameter list, trailing-return-type, and lambda body
C# Lambda ( = gt; ) - Stack Overflow All lambda expressions use the lambda operator =>, which is read as "goes to" The left side of the lambda operator specifies the input parameters (if any) and the right side holds the expression or statement block
python - List comprehension vs. lambda + filter - Stack Overflow by_attribute = lambda x: x attribute == value xs = filter(by_attribute , xs) Yes, that's two lines of code instead of one, but you clean filter expression from cumbersome lambda and by naming lambda nicely it literally becomes being read as "filter by attribute" :)
python - How are lambdas useful? - Stack Overflow Lambda expressions are becoming popular in other languages (like C#) as well They're not going anywhere Reading up on closures would be a useful exercise to understand Lambdas Closures make a lot of coding magic possible in frameworks like jQuery
