I have method that gets parameters and in this method there are calculations that change the parameters value. When returning from the method the parameters continue to other methods for more calculations.
Is there a way to pass parameter to method by reference or the only way is by i join the parameters to object and return them?
With JavaScript, and TypeScript, you can pass an object by reference -- but not a value by reference. Therefore box your values into an object.
So instead of:
function foo(value1: number, value2: number) {
value1++;
value2++;
}
Do:
function foo(model: {property1: number; property2: number}) {
model.property1++;
model.property2++;
// Not needed but
// considered good practice.
return model;
}
const bar = { property1: 0, property2: 1 };
foo(bar);
console.log(bar.property1) // 1
console.log(bar.property2) // 2
See full demo on TS Playground
You can pass property name (and object if necessary) to a method
