What does <<= mean in HTML?

HTML & CSS
1

Is it some sort of mathematical function?

2

I don’t believe HTML of any vintage supports mathematical functions as such. What context have you found it in?

3

A question, I have to describe what the program does, to what I’ve tested it’s some sort of multiplication.

4

I’d love to see that code snippet.

What you describe is not HTML or CSS.

5

That was what I was thinking. The complete question would be useful.

Here’s the code snippet
!DOCTYPE html
html
body
script
var temp = 14;
var y = 2;
temp <<= y;
document.write(temp);
/script
/body
/html

It produces a result of 56 meaning It did 14x2x2

8

That’s JavaScript embedded within a HTML page. Lookup JavaScript functions instead.

9

It is within script tags, so it’s script, not html.

Okie

That looks an awful lot like bitwise to me

No it didn’t.

14 in binary is 00001110

The << 2 moves everything two positions to the left giving 00111000 which is binary for 56
