mul in typescript

In TypeScript (and JavaScript), you can use the * operator to perform multiplication. Here is an example:

index.ts
let x: number = 5;
let y: number = 10;
let result: number = x * y;

console.log(result); // Output: 50
103 chars
6 lines

In this example, we declare two variables x and y with the number type, assign them values, and then multiply them using the * operator. The result of the multiplication is stored in the result variable, and then printed to the console using the console.log() function.

Note that the * operator can also be used to concatenate strings in TypeScript/JavaScript. If you want to perform multiplication with non-numeric data types, you will need to convert them to numbers first.
