let myDel=myArray.splice(1,1); //从索引1开始删除1个元素...let myArray=["html","css","javascript","jQuery"];
let myDel=myArray.splice(1,0,'html5','css3'); //从索引...1开始,删除0个元素,然后插入'html5'和css3
console.log(myArray) //['html','css','html5','css3','javascript','jQuery...let myArray=["html","css","javascript","jQuery"];
let myDel=myArray.splice(0,2,'html5','css3'); //从索引...1){
myArray.splice(i,1);
