In many strict languages, some advantages of non-strict functions can be obtained through the use of macros or thunks. Strict programming languages are often associated with eager evaluation, and non-strict languages with lazy evaluation, but other evaluation strategies are possible in each case. [citation needed] The terms "eager programming ...
In computer science and computer programming, a function f is said to be strict if, when applied to a non-terminating expression, it also fails to terminate. [1] A strict function in the denotational semantics of programming languages is a function f where f ( ⊥ ) =⊥ {\displaystyle f\left(\perp \right)=\perp } .
A non-strict evaluation order is an evaluation order that is not strict, that is, a function may return a result before all of its arguments are fully evaluated. [ 28 ] : 46–47 The prototypical example is normal order evaluation , which does not evaluate any of the arguments until they are needed in the body of the function. [ 29 ]
For example, Aahz Maruch observes that "Coercion occurs when you have a statically typed language and you use the syntactic features of the language to force the usage of one type as if it were a different type (consider the common use of void* in C). Coercion is usually a symptom of weak typing.
Immediately invoked function expressions may be written in a number of different ways. [3] A common convention is to enclose the function expression – and optionally its invocation operator – with the grouping operator, [4] in parentheses, to tell the parser explicitly to expect an expression.
In programming language theory, lazy evaluation, or call-by-need, [1] is an evaluation strategy which delays the evaluation of an expression until its value is needed (non-strict evaluation) and which avoids repeated evaluations (by the use of sharing). [2] [3] The benefits of lazy evaluation include:
It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. [2] It is standardized by Ecma International in the document ECMA-262 . ECMAScript is commonly used for client-side scripting on the World Wide Web , and it is increasingly being used for server-side applications and ...
A coding interview is intended to seek out creative thinkers and those who can adapt their solutions to rapidly changing and dynamic scenarios. [citation needed] Typical questions that a candidate might be asked to answer during the second-round interview include: [7] Design a GPS navigation unit for a hiker.
