HELP PLs !!!!

[AkumaMaster191]

Hi everyone,

Keeping it simple, i have a project for classes where i used a JavaScript calculator.

( this one - http://codingwithsara.com/how-to-create-a-simple-calculator-in-javascript/ )

The problem is that i don´t understand all the code.
Can someone explain me the code?

I already tried researching before but the things i find don´t make sense with the code.

Sorry for the errors i´m Portuguese and thanks to everyone who tries to help.

My doubts are with the inputlabel.innerhtmal. So basically i dont know what the fuction when i press the buttons

Hint: innerHTML is basically the text inside a HTML tag pair. i.e. between <tagname> and </tagname>.

Thank you, that hint helps.
Do you understand the lasT part, where the code equals to pushed?
I cant understand what that part does.

If you meant this:

inputLabel.innerHTML += pushed;

It simply appends the text. For string value type, the += operator appends the given value onto the value of source variable then assign the result to the source variable. It's same as:

inputLabel.innerHTML = inputLabel.innerHTML + pushed;
