The Longer Word explainer

[grasshopperexplainer]

Aim of the puzzle: Use specific instructions to complete a function.
Walk through of solution: This puzzle is the 1st in a series of lessons that will teach you how to break down word problems and real-world challenges and solve them with code.

For this puzzle, you will be getting specific instructions on how to write a function. In a future puzzle, you will be revisit this function and use it to solve a word problem, without being given specific instructions.

To complete this puzzle, complete the longer() function so that it takes 2 strings and returns whichever string is longer.
Sample code solution:
There are multiple ways to solve the puzzle.

function longer(a, b) {
    if (a.length > b.length) {
        return a;
    } else {
        return b;
    }
}
console.log(longer('signify','significant'));

Another Solution:

function longer(a, b) {
    return a.length > b.length ? a : b;
}
console.log(longer('signify','significant'));

Why in ternary code three is no return code and what is the different between code above with my code. I still confuse with usefull of return

[Grasshopper_Ben]

Hey there,

The return keyword tells the function to return a value when it is called. In this case, the function will return whichever string is longest. We can call this function inside a console.log() if we want to print the longer word, or we can store the longer word in a variable.

You function prints the longer word, but doesn’t return a value.

Hope this helps! Let me know if you have any questions.

Ben sir please help me to do this

[_friidays]

In the code block for the longer function, you can either use an if...else statement or return a if a is longer than b. It can either go like this:

function longer (a, b) {
if (a.length > b.length) {
return a;
} else {
return b;
}
}

or

function longer (a, b) {
return a.length > b.length ? a : b;
}

Hope this helps!

Why can i use console.log instead of return. ;

What difference?

[I_vivu]

Lol you😂 cant discern length of a string versus a variable

A.length and A is completely different

Why must i use return …; to notify the true answer instead of console.log
