JavaScript Uncaught TypeError: Cannot read property 'destroy' of undefined

Question

Why is it going into his if when the check is if its not undefined

 if (this.table !== undefined || this.table !== null) {
            this.table.destroy();
        }

Console error : Uncaught TypeError: Cannot read property 'destroy' of undefined

Ive tried

if(this.table)

But no luck either

Because `undefined !== null` is true – Andreas Oct 14 '17 at 16:04 — Andreas, Oct 14 '17 at 16:04

Use this

if(this.table && typeof this.table.destroy === 'function'){ 
   this.table.destroy();
}
