Builtins

Jscore is built on top of deno_core, which is a very minimal JavaScript evaluation engine which does not support things like timers, web, and more. To combat this, instead of using deno_runtime, which would make the binary size huge and increase the compile time by a lot, jscore implements most of these by itself instead.

fetch(url, {method, headers, body})

Supports:

• ok
• status
• text()
• json()

This is the simple fetch implementation of jscore. It is built for simple use cases and not for downloading large files as such. Simple actions like calling API's and extracting JSON will work seaminglessly.

Example:

// The second param is optional
const response = await fetch("https://api.github.com/repos/ewwii-sh/ewwii");
const json = await response.json();
console.log(json)

Timers

The timers like setInterval, setTimeout, etc. does not exist in deno_core. As these are simple functions, jscore has them built-in.

Example:

setTimeout example:

// Run a function after 2 seconds (2000ms)
const timeoutId = setTimeout(() => {
    console.log("This prints after 2 seconds!");
}, 2000);

// Cancel the timeout before it can execute
clearTimeout(timeoutId);

setInterval example:

let counter = 0;

// Run a function every 1 second (1000ms)
const intervalId = setInterval(() => {
    counter++;
    console.log(`Interval tick: ${counter}`);

    // Stop the loop after it runs 3 times
    if (counter === 3) {
        console.log("Stopping the interval loop.");
        clearInterval(intervalId);
    }
}, 1000);
