#9 : Understanding Optional and Default Parameters in TypeScript Functions in Hindi

Welcome, In this video, you will gain a comprehensive understanding of optional and default parameters in TypeScript functions. We will explore how to define and use optional parameters, which allow you to provide arguments selectively when calling a function. Additionally, we will delve into default parameters, which enable you to assign default values to parameters if no argument is provided.

Throughout the video, we will cover the syntax and usage of optional and default parameters in TypeScript functions, including practical examples and best practices. By the end of the video, you will have a solid grasp of these powerful features, allowing you to write more flexible and robust functions in your TypeScript projects.

Ans 1:
let arr:number[] =[8, 2, 9, 7, 4, 6];
const calculateAverage =(array[]:number):number => {
let avg = array.reduce((accum, currVal, index, array)=>{
let total = accum+=currVal;
if(index === array.length-1)
{
return total/array.length;
}
return total;
})
}
console.log(calculateAverage (arr));


Ans 2:
let arr:number[] =[8, 2, 9, 7, 4, 6];
const findMaxValue = (array[]: number):number => {
let Max = array.reduce((a:number, b:number) => a > b ? a : b);
}
let Max = findMaxValue(arr);
console.log(Max);
