One effective method for sharing your TypeScript code is by releasing it on the TypeScript playground.
It appears that you are referring to this specific example.
// It's crucial to include a generic initializer
class GenericNumber<T> {
// The TypeScript compiler will throw an error if you only define the type of the
// class property without initializing it
zeroValue: T;
add: (x: T, y: T) => T;
}
let myGenericNumber = new GenericNumber<number>(); // Make sure to provide a generic initializer
myGenericNumber.zeroValue = 0;
myGenericNumber.add = function (x, y) {
return x + y; // No errors will occur
};
Functional demo
class GenericNumber<T> {
// To address the error, consider defining a constructor
// that accepts [zeroValue] and [add] as parameters
constructor(public zeroValue: T, public add: (x: T, y: T) => T){
this.zeroValue = zeroValue;
this.add = add;
}
}
const zeroValue = 0;
let myGenericNumber = new GenericNumber<number>(zeroValue, (a,b)=>a+b);
const result = myGenericNumber.add(40,2) // Output: 42
Ensure that your function does not interact with this, as this may require additional handling.
