Why is JavaScript ASI like this? #javascript

Or you can put the semicolon after points declaration, like normal people.

Rookie mistake really. I spotted it right away. You are using js.

[AwesomeTingle]

not requiring semicolons is a stupid design choice, and we should just pretend they aren't optional.

[InanIsmailov-jlos]

i always put a semicolon. this video being another example of the headache it saves you

[kesogonzaga]

Putting a semi colon before that statement was just trying too hard to be hipster

[brainloading]

For all of you python users (we love you) the reason it crashes is because the whole code is interpreted as one line.

This is interesting, I am practicing JS and TS and these kind of content enlightens me on what I don’t know haha

[NoobietheGamer-xslc]

To destructure add a variable declaration (const) before the array and us curly braces instead of square brackets

[tutonjason]

The ultimate answer why I should go back to putting semi-colons after statements in JS. I assume this will also be the case in TS.

[MannysTechWorld]

And this ladies and gentlemen is why people make fun of javascript

[JackAttack-jnop]

The bug is that no one in their right mind would reverse an array like that. All of JavaScripts quirks are just trivia, people who use code with the bread and butter of JavaScript which works great

All of those cases are perfectly explainable by the angine not recognizing the end of the statement. You know the thing semicolons are for. Also the thing that's mandatory in most non white space sensitive languages to prevent ambiguity and weird errors.

JS is only in the users browser. That's it. It is the language I don't wanna use for anything else.

[razor-eg]

People who not using semicolons should not allowed to code in js.

Just put semicolon on every single line, or comma except for a function declaration, javascript is not compiled programming so you will never know the problem until you run it

[AdrianAlejandroSoutoMorales]

From the beginning it was solved simply by putting the semicolon after the first line... Like this:

let points = [3, 7];
[points[0], points[1]] = [points[1], points[0]]
console.log(points)

This happens because when you start the 2nd line with '[' javascript "believes" that it is the continuation of the first one.
PS: I'm not a fan of javascript, but don't make it any worse than it already is😅)

[JockelGaming]

I was Programming in Python in the Last Date and didn’t catch the missing semicolons at all 😅

[Michael-Martell]

JavaScript. Never type-spaced except when it comes to return and switch statements.

[kingbbiv]

Wait, WHAT. Need so much more information.

[thulanimthembu]

Or you can also try points.reverse()

Let points = [3, 7];

Points.reverse() //Output [7, 3]
