Usage

Example 1: Running Leziscript in "transpile" mode

import run from 'lzscript';

const code = `[[]][??!][]:![[]]>[[]][][][[]][?!][].>[??]([?][[]][]>)[??]<[?]([][[]]).>[?][[]][][]..>[??][[]].[??!]<.[???!]>[?]([[]][])[?!][[]].>[??]([?][[]][]>)[??]<[??][[]].>![[]][][][[]][].>[?][[]][][].>[][[]][][].[?????]<.`;

const result = run(code, "transpile");

console.log("Transpiled Code:", result.outputCode);
console.log("Execution Time:", result.executionTime, "ms");
Copy

Example 2: Running Leziscript in "interpreter" mode

import run from 'lzscript';

const code = `[[]][??!][]:![[]]>[[]][][][[]][?!][].>[??]([?][[]][]>)[??]<[?]([][[]]).>[?][[]][][]..>[??][[]].[??!]<.[???!]>[?]([[]][])[?!][[]].>[??]([?][[]][]>)[??]<[??][[]].>![[]][][][[]][].>[?][[]][][].>[][[]][][].[?????]<.`;

const result = run(code, "interpreter");

console.log("Output:", result.output);
console.log("Internal Pointer Position:", result.internal.pointer);
console.log("Internal Bit Array:", result.internal.bits);
