在JavaScript / TypeScript中將項目添加到數組的末尾

Question

我有這個做while循環

trucks = [];
fetchdata(){
    this.trucks = [];

    do {

     this._reportService.getReports({
        ..//pagination stuff here
        })
        .subscribe(res=> {
          this.trucks.push(res.rawdatatrucks);
        })
    } while(i<this.totalRecords);
    console.log(this.trucks)

}

以上工作正常，但數據以這種形式推送

0:[
    0:[ ...truck data stuff ],
    1:[ ...truck data stuff ],
    2:[ ...truck data stuff ],
    3:[ ...truck data stuff ],
 ],
 1:[
    0:[ ...truck data stuff ],
    1:[ ...truck data stuff ],
    2:[ ...truck data stuff ],
    3:[ ...truck data stuff ],
 ],

我期待得到的是將數據附加到數組的末尾，這樣我就可以得到

console.log(this.trucks)

     0:[ ...truck data stuff ],
    1:[ ...truck data stuff ],
    2:[ ...truck data stuff ],
    3:[ ...truck data stuff ],
    4:[ ...truck data stuff ],
    5:[ ...truck data stuff ],
    6:[ ...truck data stuff ],
    .......

來自服務器的響應是

console.log(res.rawdatatrucks);

即使在while循環的其他迭代中，也總是從0開始。

我還需要添加什么到.push方法中

使用concat而不是push 。

this.trucks = this.trucks.concat(res.rawdatatrucks);
