for (const v4 of v3) {
    const v13 = async (v14) => {
        const v24 = ``;
        const v29 = await v14;
        for (let v52 = 1; v52 == -1; v52 = v52-4096) {
            const v89 = ``;
        }
    };
    for (let v125 = 0; v125 < 9; v125++) {
        const v127 = [4,723347.8822827139];
        const v129 = v127["map"](v13);
    }
