I am having an array "options".In this array I am trying to change one element on every click.. oninit i am pushing one element in to this array and after clicking an option i need to pull out that last element and push other element in place of the last element.But getting error mentioned above.I am able to push but not able to pull out .Can anybody help me to resolve this. i have already tried with delete and remove methods but getting the same error
ngOnInit() {
this.arrayform();
x:any;
arrayform()
{
this.x=this.saveCap[this.userIndex]
console.log(this.x)
this.options.push(this.x)
console.log(this.options)
console.log(this.x)
}
arrayDel(){
console.log(this.options)
console.log(typeof(this.options))
console.log(this.x)
this.options.pull(this.x)
}
checkoptions(){
this.userIndex++
