General view and impression of death by philosophers

Death is the reality of life and every living thing have to taste the death. People can deny the God and no one can deny the death. In this post we will study different views of philosophers on death. 

1. The Epicureans: The followers of the ancient Greek philosopher Epicurus. Death is nothing to Epicureans. According to them, we fear death because of the belief that the death is painful and that the soul may have to suffer in an afterlife, but both beliefs are not true. Death is not painful it is a painless loss of the consciousness it is just like the falling asleep and therefore nothing to be feared. 
   
   
2. The Stoics: Seneca(4BCE-65CE), a Roman follower of Stoicism said that there is no need to fear death. To overcome this fear, we should think of it in a proper manner. Death reminds us that we are part of the nature and we must accept this truth.
    
3. Prophet Muhammad: Islamic prophet Muhammad (peace be upon him)(570-632 CE) taught that death is a natural part of life, urging believers to prepare for the afterlife through righteous deeds and adherence to moral principles. He emphasized hope in God's mercy, encouraging remembrance of death as a means of spiritual reflection and motivation for leading a virtuous life. 
   
   
4. Spinoza: A Dutch philosopher Benedict de Spinoza(1632-1677), wrote, a fearful an thinks of nothing less than of death, and his wisdom is not a meditation upon death but upon life.
   
   

What is processing profile in AEM

AEM cloud service supports processing profiles feature, using this we can create custom renditions for assets. This rendition could be the predefined as well as renditions craeted or generated by third party application or system.

To integrate the third party generated rendition we need to integrate with the AEM asset compute feature that is avaialble in Adobe I/O runtime and easily connect with AEM a a cloud serivce. 

Note: Processing profile option is not avaiable in local AEM cloud service SDK.

let, var and const variables in JavaScript or ReactJS

In ReactJS, the differences between let, var, and const variables are the same as in JavaScript. Here's a brief explanation of each:  

   

1. let: The let keyword declares a block-scoped variable that can be reassigned. It allows you to define variables that are limited in scope to the block, statement, or expression in which they are used. For example, you can use let variables inside loops or conditional statements.  

   Examples:

let lx;

jsvariables(lx)

function jsvariables(lx) {
    
    console.log(lx)
}

console.log(lx);


//Output

undefined
undefined

let lx = 5;

jsvariables(lx)

function jsvariables(lx) {
    lx = 7;
    console.log(lx)
}

console.log(lx);


//Output

7
5

let lx = 5;

jsvariables(lx)

function jsvariables(lx) {
    let lx = 7;
    console.log(lx)
}

console.log(lx);


//Output

let lx = 7;
        ^

SyntaxError: Identifier 'lx' has already been declared

jsvariables()

function jsvariables() {
    let lx = 7;
    console.log(lx)
}

console.log(lx);


//Output

7

console.log(lx);
            ^

ReferenceError: lx is not defined

2. var: The var keyword declares a function-scoped variable that can be reassigned. It is the older way of declaring variables in JavaScript before the introduction of let and const. Unlike let, var declarations are not limited to the block scope but rather to the function scope. This means that var variables are accessible anywhere within the function in which they are declared.  

   Examples:

var vx =12;

jsvariables(vx)

function jsvariables(vx) {
    console.log(vx)
}

console.log(vx);


//Output

12
12

var vx = 12;

jsvariables(vx)

function jsvariables(vx) {
    var vx = 13;
    console.log(vx)
}

console.log(vx);


//Output

13
12

var vx = 12;

jsvariables(vx)

function jsvariables(vx) {
    vx = 13;
    console.log(vx)
}

console.log(vx);


//Output

13
12

var vx;

jsvariables(vx)

function jsvariables(vx) {
    var vy = 12;
    console.log(vy)
}

console.log(vx);


//Output

12
undefined

var vx;

jsvariables(vx)

function jsvariables(vx) {
    vx = 12;
    console.log(vx)
}

console.log(vx);


//Output

12
undefined

var vx;

jsvariables(vx)

function jsvariables(vx) {
    vx = 12;
    console.log(vx)
}
vx = 16;
console.log(vx);


//Output

12
16

3. const: The const keyword declares a block-scoped variable that cannot be reassigned. It is used to declare constants, which are variables that cannot be changed after they are declared. const variables must be initialized with a value at the time of declaration, and you cannot reassign them later.  

   Examples:

const cx = 12;

jsvariables(cx)

function jsvariables(cx) {
    console.log(cx)
}

console.log(cx);


//Output

12
12

const cx;

jsvariables(cx)

function jsvariables(cx) {
    console.log(cx)
}

console.log(cx);


//Output

const cx;
      ^^

SyntaxError: Missing initializer in const declaration

const cx;
cx = 12;
jsvariables(cx)

function jsvariables(cx) {
    
    console.log(cx)
}

console.log(cx);


//Output

const cx;
      ^^

SyntaxError: Missing initializer in const declaration

In general, it is recommended to use const for variables that will not be reassigned, let for variables that will be reassigned within their scope, and avoid using var as it has some potential issues related to scoping and hoisting. However, the choice between let and const ultimately depends on your specific use case and requirements.
