我找到了一种使用 arrayName.slice(start, end) 显示数组一部分的方法，我创建了一个函数将开始和结束提供给切片方法，这样我就可以将它与 onClick 按钮一起使用以单击接下来的 3 个元素以在 HTML 中显示。

我的问题是增量函数不是从零（0）开始，而是从 3-6 开始，当我按下下一步时，它从 6 到 9 开始。它工作正常但不是从零开始

    const array = ["a1","a2","a3","a4","a5","a6","a7","a8","a9","a10","a11","a12","a13","a14","a15"]

let next = {
        start: 0,
        end: 0,
        incrementby: 3,
        inc() {
          this.start = this.start = 0 ? 0 : this.start + this.incrementby;
          this.end = this.start + this.incrementby;
          console.log(this.start, this.end);
          displayHadith(this.start,this.end)
        },
      };
      
 function displayHadith(start,end) {
        var container = document.querySelector(".container");
        container.innerHTML = ""
        let some = array.slice(start, end);
         for (let element of some) {
          container.innerHTML +=`
          <div class="sharh" >${element}</div>
          `
         }
        }
<button onclick="next.inc()">clickNext</button>
<div class="container"></div>
