Checking the parameters passed to a function in Typescript: A step-by-step guide

Currently, I am working with Typescript and then transpiling my TS code into JavaScript. However, I have encountered an issue that I am struggling to resolve. The error message I am facing is as follows:

Error Found in TypeScript on Line:2 - error TS2304: Cannot find name 'arguments'

Here is the snippet of my TypeScript code causing the problem: 

1        function testSomething() {
2            var paramsPassed = arguments;
3            console.log("Received Parameters : ", paramsPassed);
4            return arguments.length;
5        }
6
7        const result = testSomething("this", "is", "a", "demo");
8        console.log("Expected Output: " , result);

I am unsure of how to handle this error or where to look for a solution. Any help would be greatly appreciated.

Answer №1

The "arguments" keyword is only valid in JavaScript files and not in TypeScript files.

To make it work, modify the function as shown below:

function testSomething(... arguments: string[])
