JavaScript ES6 Tutorial #4 - Default Parameters

Yo dudes, in this JavaScript ES6 tutorial, I'll introduce you to default parameters and how we can use them as a fallback option when not other parameters are passed to our functions explicitly.

Great tutorial. how could this be used in a constructor prototype function?

[temprmj]

I love how ES6 is behaving more and more like Python

[necrophage]

Can you set default objects as parameter and override them? I am used to doing this in PHP. Seeing that ES6 now has default parameters is exciting.

BTW, It's not 40, lol, I like your tutorials, thx a lot!

Good tuts but you missed off how you pass in say just the belt colour?

[mayankgangwal]

Also works with functions as a default params like a charm

function callSomething(hey = heyNinja()) {
return hey;
}

function heyNinja() {
return 'Hey Ninja';
}

callSomething(); //Hey Ninja

Peace.

but how can you skip the middle parameter ??? logNinja("shaun", , 40); so it can insert default "red"???

Great tutorial, however it can be shorter. There's no need to explain further after 2.00 mark
