TypeScript error when using the Spread operator?

Question

Whenever I use the spread operator such as below

public drawTextTest(p1: number, p2: number, p3: number):void {
    console.log(p1, p2, p3);
}
let array = [         


        

Answer 1

Newer versions of TypeScript should be figuring this out through flow analysis but you should be able to get the code working by manually typing the array to the following way to ensure the min length:

function drawTextTest(p1: number, p2: number, p3: number):void {
    console.log(p1, p2, p3);
}
let array: [number, number, number] = [2, 2, 5];
this.drawTextTest( ... array );
