In computer programming, the pyramid of doom is a common problem that arises when a program uses many levels of nested indentation to control access to a function. It is commonly seen when checking for null pointers or handling callbacks. [1] Two examples of the term are related to a particular programming style in JavaScript, [2] and the ...
Design by contract ( DbC ), also known as contract programming, programming by contract and design-by-contract programming, is an approach for designing software . It prescribes that software designers should define formal, precise and verifiable interface specifications for software components, which extend the ordinary definition of abstract ...
Assertion (software development) In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true ...
v. t. e. The MECE principle, ( mutually exclusive and collectively exhaustive) is a grouping principle for separating a set of items into subsets that are mutually exclusive (ME) and collectively exhaustive (CE). [1] It was developed in the late 1960s by Barbara Minto at McKinsey & Company and underlies her Minto Pyramid Principle, [2] and ...
Learning pyramid. The learning pyramid (also known as “the cone of learning”, “the learning cone”, “the cone of retention”, “the pyramid of learning”, or “the pyramid of retention”) [1] is a group of ineffective [2] learning models and representations relating different degrees of retention induced from various type of learning.
Twin pattern. In software engineering, the Twin pattern is a software design pattern that allows developers to model multiple inheritance in programming languages that do not support multiple inheritance. This pattern avoids many of the problems with multiple inheritance. [1]
Java is loaded from compiled bytecode, while JavaScript is loaded as human-readable source code. Java's objects are class-based, while JavaScript's are prototype-based. Finally, Java did not support functional programming until Java 8, while JavaScript has done so from the beginning, being influenced by Scheme. JSON
Scientists from the Oak Ridge National Laboratory, a descendant of the original lab that discovered the element back in 1945, implemented a new process last year that allowed for the creation of a ...
