Function in j.s

Functions in javascript is the reusable blocks of code designed to Perform specific task.Instead of writing the same code again and Again you can put it inside a function and call it whenever needed.

  • SIMPLE IDEA

A function is like a machine,You can give a inputs it's called (parameters),it's processes and gives to back a output(called a return value).

  • SYNTAX

function ogadd(boys, girls);
return boys + girls;
}

  • Function is the keyword referring that we are writing a function
  • ogadd is the name given to the function it's used to call the function
  • boys and girla are the parameters inputs of the function it's like a Variable
  • return is the keyword if can used to the return the result once the Function is called

  • EXECUTION

let result = ogadd(25, 20);
console.log(result);

  • Once if you can calling the function is 25 and 20 are the arguments It's take the place of parameters boys and girls
  • It's runs the function addition operation returns the value 45 is Stored in the variable result
  • We have a returned the value it will stored in the variable result

  • SIMPLE UNDERSTANDING

  1. Start with function is defined - ogadd
  2. Next function is called - ogadd(25, 20)
  3. Then assigned the value for boys and girls - boys = 25, girls = 20
  4. Calculation - 25 + 20 = 45
  5. The function returns 45
  6. The return value 45 is stored in result
  7. finely printing the result to the console.
