Select_layername is it corect?

Hello, kamalakas .
You’re right, sorry for the delay, but you know, because of work, I work as a chartered accountant at Ford and in my spare time I practice my hobby.

This is clean and working code :100:

/////////////////////////////////////////////////////////////////////////////////////
///////// MY WORKE MOHAMAD FATHI   🚀🚀  BOOST_Show_Hide🚀🚀    /////////

// BOOST_Show_Hide...(How to change layer BOOST_Show_Hide by name inside a group).

const BOOST_Show_Hide = async () => {
    let wantedLayer = "BOOST"
    await ExecuteAsModal(async () => {
        let doc = app.activeDocument;
        doc.layers.forEach(layer => {
            if (layer.kind == "group") {
                layer.layers.forEach(gLayer => {
                    //now looping through group layers : one level deeper
                    if (gLayer.name == wantedLayer) {
                        //layer found
                        // you can also check its kind if you like to
                        gLayer.visible = !gLayer.visible
                    }
                })
            } 
        }) 

    }, { "commandName": "layer visible..." }) //executeAsModal :: END
    console.log("BOOST_Show_Hide Result!!!")
}
