While Assembly is a language able to give instructions to the computer hardware, WebAssembly is an Assembly-like language able to drive a portable virtual stack machine. At present, not only all major browsers run an implementation of this VM, but WebAssembly bytecode can a...
Data structures that strongly require to be thread-safe are best candidates to become immutable objects. Moreover, as programmers can write mutable code that behaves in an immutable fashion, how to best achieve immutability? Does this programming approach really affect performance?
Forth is an untyped programming language that heavily relies on the stack: data will be stored onto the stack before they are operated upon. Forth is the perfect programming language for hardware engineers:
Immutability means that variables cannot be modified once they have been set with data, which prevents unwanted changes from occurring.
The concept of immutability is strictly connected with pure functions. In pure functions:
Each time an element of the DOM changes, the browser will have to recalculate elements and styles and also it might have to re-flow the page. The following is the typical workflow:
Recalculate Style → Layout → Paint
