Chapter 42- Dangerous Aside (Automatic Semicolon Insertion)

Notes

Semicolons are optional in core js
The syntax parser in js engine injects automatically the semicolon at the end of required syntax






Example 1
function getPerson(){
	return
	{
		firstname:'Tony'
	}
}

console.log(getPerson()); //gives error as it adds semicolon after return
Following will work
function getPerson(){
	return {
		firstname:'Tony'
	}
}
