This button will be on the upper left side of your screen. The name of your function should be the name of your file, so when you save this new script file it will be the name of your file. There are two ways of writing functions:

In this example, we are writing a function to add two numbers. Let’s see a basic typescript function syntax (with two arguments) function functionname (arg1: With a simple script, the function is simply declared in the same file as it is called.
