应该怎么样解决这个格式问题？

【已解决】利用string.trim() 或string.replae()来删除所获取字符串的空格

function printInfo(courses){
        courses.forEach(function(currentCourse){
        var chapterTitle = currentCourse.chapterTitle;
        // console.log(chapterTitle.trim()+"\n");
        console.log(chapterTitle.replace(/\s+/g,"")+"\n");
        
        var videos = currentCourse.videos;
        videos.forEach(function(video){
            // console.log("【"+ video.id.trim() +"】"+video.title.trim() +"\n")
            console.log("【"+ video.id.replace(/\s+/g,"") +"】"+video.title.replace(/\s+/g,"") +"\n")
        });
    });
}
