Argument of type 'number' is not assignable to parameter of type 'never' why i am getting this error?

Question

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
 showSecret = false;

logArray = [];

onToggleDetails()
{
this.showSecret = !this.showSecret;
this.logArray.push(this.logArray.length);
}

}

while running the above code, Angular is giving below error Error: src/app/app.component.ts:16:20 - error TS2345: Argument of type 'number' is not assignable to parameter of type 'never'.

this.logArray.push(this.logArray.length);

Answer 1

The compiler wants you to declare the type of your logArray. Try following:

logArray: number[] = [];

Let me know if it works:)
