    Class Sandbox

    Isolated JavaScript context within the same runtime. Each Sandbox has its own global scope — variables and modules in one sandbox cannot pollute another or the main context.

    const engine = import.meta.use('engine');
    const sb = new engine.Sandbox();
    sb.call('var x = 42');
    sb.call('x'); // 42
    Index
