What do I need to do to ensure that an object I assign in observable is not affected by updates angular?
0
myObj : = ;
tmpObj: = ;
ngOnInit()
this.myService.getData().subscribe(
data =>
this.myObj = data.values;
this.tmpObj = Object.assign(, this.myObj);
)
updateData(prop, val)
this.myObj[prop] = val;
When I call updateData method and update the property of myObj, this change affect the tmpObj. But I don't want the tmObj object to be affected by these changes. What am I supposed to do for this?

You need to make a deep copy of the object (array) stackoverflow.com/questions/597588/…

if is an array you can do:
this.myService.getData().subscribe(
data =>
this.myObj = data.values;
this.tmpObj = data.values.slice();
)
or you can do:
this.myService.getData().subscribe(
data =>
this.myObj = data.values;
this.tmpObj = data.values.map(x => Object.assign(, x))
)
