How do I re-assign the else if in javascript to function the same but typed as elif?

javascript else if
javascript if statement multiple conditions
javascript if else shorthand
if-else if java
else if c++
html conditional statements if else
if...else statement
html if else tag

I'm currently doing some JavaScript programming and don't like having to type else if everytime I need to use it. I would much rather just type elif. I have done tons of research and don't know how I could get something like this... look at code ... to work where I can still say elif, but it is recognized as else if and I would be able to use it without the program.

elif = else if;
let x = 20;
if (x >= 21) {
  console.log('psych bwah!');
} elif (x <= 19 ) {
  console.log('umm... nope try again bud!');
} else {
  console.log('ladies and gentlemen we gotem!');
}

I really want this to work so badly. And it would be so mind pleasing to understand how to rewrite pre-made code in terms that I want to use. Another example of what I'm trying to accomplish would be re-assigning the console.log() printing function to something shorter but still does the exact same thing, maybe c.l() as a shorter version, just for example though.

Having the ability to assign already usable normal JavaScript code to my own version of code is the task I guess I am trying to accomplish, if that makes sense. This way I can shorthand it and make everything way faster than I'd be able to before. So what I am really looking for is a better/working way, because my current method seen above in the code doesn't work, is maybe some form of a method or other way of changing the name of an if...else keeping the same function just typed/said different in code.


Answer:

Yes, it's possible.

As a note, it's not a great idea to do this for any production projects for a multitude of different reasons, however, it's a rather simple process for toy code or snippets.

How:

You can create a text/template script tag, parse it for Regular Expressions or Plain Text - just like any other String - replace it with whatever you would like, then place it in a Function constructor and call it.

A longer explanation I wrote in an article a while back can be found here: https://medium.com/wdstack/understanding-javascript-micro-templating-f37a37b3b40e

A larger example with a couple of different code adjustments ( for instance instead of if(a === b || a === c) you can write if(a === b || c) ) can be found here: https://codepen.io/zfrisch/pen/ENpvOq


Basic example of Elif:

var scriptText = document.querySelector('#microTemplate').innerText,

parsed = scriptText.replace(/elif/g, "else if"),

fn = new Function(parsed);

fn();
<script id="microTemplate" type="text/template">
  let a = 5;
  
  if(a < 5) console.log("a is less than 5");
  
  elif(a === 5) console.log("a is 5");
  
  else console.log("a is greater than 5");
</script>

JavaScript if else else if, JavaScript if else and else if. ❮ Previous Next ❯. Conditional statements are used to perform different actions based on different conditions. Conditional Statements. In JavaScript we have the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true Use else to specify a block of code to be executed, if the same condition is false


You can't assign a statement to a variable, you can only assign an expression.

if,else, and else if are all statements (along with try/catch, switch, for, while, etc..)

So in short, there is no real way that bit can work.

To alias an existing function you simply assign the existing function to a new variable, like so:

const c = {}
c.l = console.log
c.l('console','.','log','arguments')

JavaScript if/else Statement, The if/else statement executes a block of code if a specified condition is true. The if/else statement is a part of JavaScript's "Conditional" Statements, which are used to if the same condition is false; Use else if to specify a new condition to test, If time is less than 10:00, create a "Good morning" greeting, if not, but time is  In JavaScript we have the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true; Use else to specify a block of code to be executed, if the same condition is false; Use else if to specify a new condition to test, if the first condition is false


I believe you could do it for console.log. You would essentially be creating a function to console.log. Yeah its quicker to type but will be preforming 2 functions.

let x;
const y = "hello world"

const cl = function (x) {
  console.log(x)
 }
 
 
 // Function call.
 cl (y)

ifelse, The if statement executes a statement if a specified condition is truthy. function testNum(a) {. 2 Multiple ifelse statements can be nested to create an else if clause. Do not confuse the primitive Boolean values true and false with in a conditional expression, because the assignment can be confused  The do/while statement creates a loop that executes a block of code once, before checking if the condition is true, then it will repeat the loop as long as the condition is true. The do/while statement is used when you want to run a loop at least one time, no matter what. JavaScript supports different kinds of loops:

The elif statement allows you to check multiple expressions for TRUE and execute a block of code as soon as one of the conditions evaluates to TRUE. Similar to the else, the elif statement is optional. However, unlike else, for which there can be at most one statement, there can be an arbitrary number of elif statements
