Is it important using semicolon?

Question

Is it important using semicolon ; ?
Because my code below is also working well (without semicolons)↓↓

var x = 100
console.log(x)

Sorry for my bad engish.

Answer 1

Yeah, but not in javascript.
It's not necessary to write an` ; `at the end unless you are writing two lines of code in the same line.
I mean

var x = 100
console.log(x); console.log(x+2)

Answer 2

MD. Ferdous Ibne Abu Bakar Yeah it's important and the reason why your code is running well is because a lot of IDEs have the automating system wich can run the code without using semicolon .
But it's important to use it in order to get used on it.
Sorry for my bad english too😅😅😅

Answer 3

Yeah, like Simba says that it's useful in writing 2 codes on the same line, it's true.

But in languages like JAVA it is NECESSARY, without it your code will crash, so keep habit of using semicolons👍🏻

Answer 4

Thank you all 😍

Answer 5

In low-level languages like C, the statements are separated by a semicolon instead of a new-line, unlike Python.
