var arr = [{"cid":"1","course_name":"CS","subcode":"CS-601","subname":"Microprocessor","semester":"6"},{"cid":"2","course_name":"CS","subcode":"CS-602","subname":"PPL","semester":"6"},{"cid":"3","course_name":"CS","subcode":"CS-604","subname":"computer networking","semester":"6"},{"cid":"4","course_name":"CS","subcode":"CS-603","subname":"software Engineering","semester":"6"},{"cid":"5","course_name":"CS","subcode":"CS-601[P]","subname":"Microprocessor practical","semester":"6"},{"cid":"6","course_name":"CS","subcode":"CS-604[P]","subname":"Computer networking practical","semester":"6"},{"cid":"22","course_name":"ME","subcode":"ME-301","subname":"motar","semester":"3"},{"cid":"23","course_name":"ME","subcode":"ME-302","subname":"friction","semester":"3"},{"cid":"24","course_name":"ME","subcode":"ME-301[P]","subname":"motar practical","semester":"3"},{"cid":"25","course_name":"ME","subcode":"ME-302[P]","subname":"friction practical","semester":"3"},{"cid":"26","course_name":"CE","subcode":"CE-701","subname":"Design of hydraulic Structure","semester":"7"},{"cid":"27","course_name":"CE","subcode":"CE-702","subname":"Advances Structrued design 2","semester":"7"},{"cid":"28","course_name":"CE","subcode":"CE-701[P]","subname":"Design of hydraulic Structure practical","semester":"7"},{"cid":"29","course_name":"CE","subcode":"CE-702[P]","subname":"Advances Structrued design 2 practical","semester":"7"},{"cid":"45","course_name":"AU","subcode":"AU-502","subname":"AUTOMATION TOOL","semester":"1"}];

var arrIncludeCS = [];
for (let i = 0; i < arr.length; i++){
  if( arr[i].course_name =="CS"){
      arrIncludeCS.push(arr[i])
   }
}
console.log(arrIncludeCS)
