créate a funnxtu in javascript

To create a function in JavaScript, you can use the following syntax:

index.tsx
function functionName(parameter1, parameter2) {
  // code to be executed
}
75 chars
4 lines

For example, let's create a function called printFunnxtu that takes two parameters (a string and a number) and prints the string a certain number of times based on the number parameter:

index.tsx
function printFunnxtu(str, num) {
  for(let i = 0; i < num; i++) {
    console.log(str);
  }
}
95 chars
6 lines

This function uses a for loop to iterate num times and print the str argument on each iteration. Now you can call this function with a string and number of your choice:

index.tsx
printFunnxtu("Hello Funnxtu!", 5);
35 chars
2 lines

This will print "Hello Funnxtu!" five times in the console.

You can also add control flow and logic to your function to make it do different things based on certain conditions.
