I saw in the question How to implement memoization in a PHP function? appears the term" memoization ".
The first impression I had is that this term was related to "memorizing" or "avoiding reprocessing". Is it just that or is it something more comprehensive?
Where did this term come from and what does it mean?
Can any programming language use this "memo"?
The etymological origin is the same as the term "memorization", the two cognates . From the Wikipedia article ,
The term "memoization" was invented by Donald Michie in 1968 and is derived from the Latin word "memorandum", generally truncated as "memo" in English, and thus carries the word "memo". meaning of "Turning the results of a function into something to be remembered". While "memoization" can be confused with "memorization" (because they are etymological cognates), "memoization" has a specialized meaning in computing.
Memo is a subtype of caching .
What difference does it make when installing a module via NPM, using the --save?
When using npm install nomedom module, it installs and writes the modules in the project folder.
I did not understand then when to use npm install nomedomodulo --save
Someone to help me?
The %code% saves the package in the %code% file, which serves as a reference for your project. Soon when you use the command %code% all modules that were installed with %code% will be installed without the need to set them one by one.
Referring to npm install documentation :
-S , - save : Package will appear in dependencies.
