Why is this code not functioning properly in TypeScript?
For example:
views: any[] = [360001232825, 360001232845, 360001217389];
myArray:any[];
for (var i = 0; i < this.views.length; i++) {
this.subscription = this.dataService.getMyData(this.views[i]).subscribe(data => {
this.myArray[this.views[i]]=data;
});
}
Instead of using .push, I want to insert data into my array at a specific index.
To add an element, you can use the splice method. However, it is recommended to utilize a Map or object for better organization.
let arr = ["one", "two", "four", "five"];
console.log("Original Array:\n" + arr);
arr.splice(2, 0, "three");
console.log("Updated Array:\n" + arr);Here's another example:
let labeledIndexes = [1564789, 234895, 249846];
let mapObj = {};
let info = "example data";
labeledIndexes.forEach((value, index, array) => {
mapObj[value] = info + " added at " + value;
});
console.log(mapObj);The 'mapObj' acts similar to 'this.myArray', 'info' serves as the parameter, and 'labeledIndexes' represents the view array. Hopefully, the code clarifies itself.
