Functions in JAVASCRIPT

• Function includes set of instructions
• Function is a block of code performs is a specific task to avoid rewriting code again and again
• It is easy to reuse
• Function has parameter and return value (e.g) function Make Biriyani ( Rice,chicken ) { Console.log (" chicken Biriyani"); }

EXECUTION:-

1.Declare function and and give parameters( rice and chicken)
2.store the given things in function
3.And print result

NOTES :

• Arguments in function are very flexible
• If javascript called missing arguments it remains undefined
• Returning function to use a same value to write a same code again and again
• We can call the same function multiple times
• Variables inside a function cannot be used outside of function
