CodePudding user response：

curarr.splice(3, 0, ...otherObj)

CodePudding user response：

With the splice method, you can add or delete elements from a specific index.

const currarr = [{id:1,name:"abc"},{id:2,name:"efg"},{id:3,name:"hij"},{id:4,name:"klm"},{id:5,name:"nop"}];

const otherObj = [{id:6,name:"fdf"},{id:7,name:"gfg"}]


currarr.splice(3, 0, ...otherObj)

console.log(currarr)

CodePudding user response：

The slice() method returns a shallow copy of a portion of an array into a new array object selected from start to end (end not included) where start and end represent the index of items in that array. The original array will not be modified.
