three dots ('...') before the variable name, as seen in spread operator. A REST parameter must be of an array type or we will get a compilation error. Theoretically, there is no specific limit to the maximum number of arguments. let addInputValues = function(...values: number[]): ...

it will show like in this format. But if we use the spread operator, JavaScript letboth = [9, …x, …y,10]; it will render our array in original, JavaScript console.log(both);//[9, 5, 7, 3, 8, 10] you can see these three dots with name of variable (…x) is called sprea...

It uses the keyof operator to get a union type of all the keys in T that are strings or numbers. It recursively applies the Paths type to the remaining values. It returns a union type of all the resulting paths. The Paths type can be used this way: interface Package { name: string;...

An alternative for rest arguments would be to add three dots (f(x: "foo", ...y: 3, 4, 5)). I first didn't think about this because the name of the argument makes already clear that it can except multiple arguments: list.insert(index: 3, values: 7, 8, 9); // values (...
