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 ...
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:
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 ]
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 } .
ECMAScript is commonly used for client-side scripting on the World Wide Web, and it is increasingly being used for server-side applications and services using runtime environments such as Node.js, [3] Deno [4] and Bun.
In his book The Humane Interface, Jef Raskin defines modality as follows: "An human-machine interface is modal with respect to a given gesture when (1) the current state of the interface is not the user's locus of attention and (2) the interface will execute one among several different responses to the gesture, depending on the system's current state."
