find the square root of a number in typescript

To find the square root of a number in TypeScript, you can use the Math.sqrt() function. The sqrt() function returns the square root of a number.

To use the function, you first need to define the number you want to find the square root of. Then you can call the Math.sqrt() function and pass in the number as an argument.

Here's an example:

index.ts
const num: number = 9; // define the number
const squareRoot: number = Math.sqrt(num); // find the square root
console.log(squareRoot); // output: 3
149 chars
4 lines

In this example, we define the number 9 and store it in the num variable. We then call the Math.sqrt() function and pass in num as an argument to find the square root. The result is stored in the squareRoot variable, which we then log to the console. The output of this code will be the number 3, which is the square root of 9.
