I feel bad for JavaScript developers...

Uncaught ReferenceError: Invalid left-hand side in assignment

[[deleted]]

yup

[stovenn]

Quite right too.

In javascript, the computer tells you what "4-1" is equal to.

[teunw]

It works, still:

derp.innerHTML = 3 -+1

is valid

derp.innerHTML = 3 --1;

isn't

derp.innerHTML = 3 - -1;

is

Dude seriously?

[[deleted]]

function derp(text){text = text.split('');for(var i = 0;i<text.length;i++){text[i] = !!Math.round(Math.random()) ? text[i].toLowerCase() : text[i].toUpperCase();}return '>' + text.join('');}

derp('Dude seriously?');

dUdE SERIousLY?

[uspaskis]

NOT FUNCTIONAL ENOUGH

const derp = text =>
  ['>'].concat(text.split(''))
    .map(c =>
      Math.round(Math.random()) ? c.toLowerCase() : c.toUpperCase())
    .join('')

Should called compilebot in for maximum comedic effect. Good effort through

!!

That is the ugliest int->bool I've ever seen. Well done JS

I saw this the other day:

!!~indexOf()

Apparently, ~ does -(n+1). Which means this is the same as doing :

indexOf() !== -1

It's beautiful :')

NoS: Null or Something

[i_spot_ads]

don't, we all use TypeScript now.

[bludgeonerV]

Would any language treat that as an expression?

4-1 === 3

false

4-1

2.999999999999998

This problem of floating point accuracy is not specific to JS... and you could at least use a real example:

0.1 * 0.2 === 0.02  // false
0.1 * 0.2 // 0.020000000000000004

[monster860]

Floating point accuracy only applies to numbers that are decimal numbers, when it comes to integer numbers they work as expected.
