Binding element 'index' implicitly has an 'any' type

Question

Using the demo project of angular2-mdl as a guide I ported the tab component and tried to implement it as follow:

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

@         


        

Answer 1

use any or specific type of the variable like ( numbers,string,etc )

public tabChanged(index:any): void {
    this.activeIndex = index;
}

Answer 2

It is a check of the type script compiler. You can either remove the check or specify explicitly the any type in the declaration (answer from @Thyagu). In the tsconfig.json file, you could change the line

"noImplicitAny": false,

to

"noImplicitAny": true,

Answer 3

for an object, you need to declare the type as

{index} : {index:any}
