Javascript Journey

Hey there,

I have been thinking about organising things i learned and still learning at a single place like this.

So instead of going to google and then stack overflow i can directly come right here.

Wow . Brilliant idea . Nobody would have never thought about this. Classic.

I know you may think like that. But wait. There is more. I bet you can find atleast one new thing from here.

Lets start with some very basic one.

What is a closure?

So baby pull me closure in the back seat of your ... nop not that.

A closure is basically an inner function that has access to the outer or enclosing function's variables.

So the canIGoToMars returns the inner function firstThingFirst.
canIGoToMars function has a variable in its local scope called greeting.
firstThingFirst function has access to the greeting variable . It console logs the greeting variable plus the name variable we pass into the canIGoToMars function.

An example of closure.

Lets wrap up with a real complex javascript scenario only god can answer.

How to console a certain word without using its entire letters

Say here its 'banana'. We can use most likely

console.log(('b' + 'a' + + 'a' + 'a').toLowerCase());

Developers are still researching on this.

If we can go through their updates it would be

+'a' resolves to NaN ("Not a Number") because it coerces a string to a number, while the character a cannot be parsed as a number.

Thats it for now.
