easylang VS calculator

Hi. I made Easylang to help beginners get started with programming. It is open source.

Why I think Easylang is for beginners better than Python.

A somewhat old-fashioned programming language

easylang is a rather minimalistic simple programming language. Because of the clear syntax and semantics it is well suited as a teaching and learning language. Functions for graphic output and mouse input are built into the language.

The language is written in C and is open source. Main target platform is the web browser using WASM. However, it also runs natively in Windows and Linux.

The one-pass parser and compiler is quite fast. In the Web IDE, each time the Enter key is pressed, the program is parsed and formatted up to the current line.

The AST interpreter is fast, much faster than CPython for example.

The language is statically typed and has as data types numbers (floating point) and strings and resizeable arrays. Variables are not declared, the type results from the name (number, string$, array[]).

Uses: Learning language, canvas web applications, algorithms.

For example, I solved the AdventOfCode tasks with easylang.

I've been playing with classic BASICs recently, especially dialects for pocket calculators. Here are some random thoughts from this exercise:

"PRINT USING" is terrible (vs. C's formatted strings).

"INPUT A" is not versatile enough. I should be able to prompt with the current value of A, so user can hit enter to keep the current value. None allow you to print the current value of A (INPUT STR$(A)+">",A does not work anywhere). Some dialects allow you to retain A: TRS-80 BASICs do it. MS-BASIC sets A to zero if user just hits Enter.

Pocket computer BASIC allows you to enter an expression as a response to INPUT, such as A+1.

Modern calculators allow you to enter equations in textbook format. I kind of think modern BASICs should support this- no reason to be stuck in the early 60s teletype world.

Pocket computer BASIC allows you to bind programs to keys (or at least entry points to keys: you can have a key jump to a line with a key-label).

Pocket computer BASIC allows you to read the last entered value (AREAD command in Sharp).

Here is a benchmark which shows why these things can be important, at least in the realm of pocket computers and calculators:
