    You can’t replace them with different characters, but You can replace the last _ with the following

    let updateStreamSelectedCourse = 'mech (electronics)'.replace( /([^w]+)/g, '_', ).replace(/_$/,"");
console.log(updateStreamSelectedCourse)

    /_$/g,'' should be what you need :

    let updateStreamSelectedCourse = 'mech (electronics)'.replace( /([^w]+)/g, '_', ).replace(/_$/g,'');
console.log(updateStreamSelectedCourse)
