4:28 :
error cause the variable is declared as Constant.
if the variable was declared like : let x = 10, then the value would have been 10, as it's a post increment. So, if we put another console.log after the first console.log then the value would be 11

var x = 2;
console.log(x++);
let y = 2;
console.log(y++);
const z = 2;
console.log(z++);

Terminal:

TypeError: Assignment to constant variable.

const ki value change nahi hoti ha is liye error print hoga k const ki value increase kr rhe ho iske liye apko var use krna parega aur jab var use kroge to tab b ans 10 he print hoga q k ++increment krta ha just phr next step ma agar ma console.log(x) print kro to phr 11 print hoga...

[KhanRehan-xkot]

Sir please node js se Angular ka project bnaiga please

[creativedev]

x++ means x = x + 1;
And you can't reassign the value in const so Assignment to constant variable error occurred.

[ranjitgupta]

agar const k jagah let ya var use kre, then error to nhi aayega lekin output 10 he aayega, aisa q ?? 11 aana chahiye na

[mohdshahbaz]

Error aayega because constant variable h and constant variable value cannot change.

[kumargourav]

Can we say that REPL is just shell script for Node

[anilrajmeena]

11, to nahi ho skta kyoki ye loop me nahi hai

Error aayega
