for 循環在 typescript javascript 中不起作用

Question

我有一個對象數組，其中包含從和到這樣的時間

[{from:2.3,to:4.5},{from:4.5,to:6}]

現在我試圖循環這個來檢查我的值這里的問題它只得到第一個我用 JavaScript 嘗試過的項目它工作正常但是當我使用 typescript 它沒有按預期工作它只是繼續返回第一個我的數組上的元素並停止所以可能是什么問題

const freeSchedule = await ConsultFreeTime.findOne({consultantId:"123"})
            .then(schedule=>{
               
                schedule.week[day].sort((a:any,b:any ) => a.from - b.from);
                let week = schedule.week;
                if (week[day]) {
                    let timesRange = week[day];                       
                    let checkData = [];

                    // get number of sessions
                    let sessionsNumber = range / 15 - 1;
                    let back=0;
                    
                 // the problem is on that loop
                   for (let i = 0; i < timesRange.length; i++){
                       if (timesRange[i].from === startTime.from){
                            startTime = timesRange[i];
                            back = i;
                           
                        if (startTime.busy.includes(date) && appointmentCheck) {
                            return {

                            }

                        console.log('11111',timesRange[i + sessionsNumber + 1])
                        if (timesRange[i+ sessionsNumber + 1]) {
                            // this will hold the rest time after patient duration end
                            let newUpdate = timesRange[i + sessionsNumber + 1];
                            // send the total time to the admin panal
                            updatedTime = {

                          break;

                       }else {

return將始終停止循環的執行。 看看這個答案： https://stackoverflow.com/a/11714515/4716214也許你想用forEach代替。
