JavaScript中根据ID删除数组对象的两种常用方法

arr.splice(arr.findIndex(item => item.id=== 1), 1)

 this.list = this.list.filter((item) => {
      return item.id != id
      });

const arr = '1'
 
const allArr = [
    {id:1,name:'张三'}
    {id:4,name:'李四'}
]
 
最终结果：
    
    //screenArr = [{id:4,name:"李四"}];
 
实现如下：
    
    const screenArr = allArr.filter((item) => {
          return !arr.includes(item.id)
    });

array.filter(function(currentValue,index,arr), thisValue)  //filter() 不会改变原始数组

[1, 2, 3].includes(2);     // true
