TypeScript - Rest Parameters Functions

Rest Parameters –

The Rest parameters do not restrict the number of values that we can pass to a function and the passed values must be the same type otherwise throw the error.

For Example as,

//Rest Parameters
let addNumbers = function(...nums: number[]) {
    let p;
    let sum: number = 0;

    for (p = 0; p < nums.length; p++) {
        sum = sum + nums[p];
    }

    return sum;
}

//The Result
addNumbers(1, 2);
addNumbers(1, 2, 3);
addNumbers(1, 12, 10, 18, 17);
