Passing dynamic data through React components using Props.
Hi, I faced this error while trying to incorporate "Dark Mode". My project stack included : Next JS, Tailwind CSS. This error could be mitigated in the following ways (atleast it worked for me): Remove the "require" keyword in post.config.js file ...
Declarative programming is pattern which executes the codes without disclosing it's implementation.
In layman terms "Doing without doing".
Assume the following imperative example :
If I were to explain the code to a kid then i would explain it in this way :
const number = [0,1,2,3,4,5];
const findcube = function(number) { }
Inside the block
{ } -> is known as Block.
Block Start
const cube = [ ];
for (let i = 0; i < number.length; i++)
i < number.length The code will run till there's no number left to find out the cube for. number.length represents the length of the number array
{
cube[i] = Math.pow(number[i], 3);
}
return cube;
Block ends
Outside Block
console.log(findcube(number));
Output in the console :
At every step, the implementation of each and every line was described.
How about programming using declarative function without disclosing it's implementation.
Map function : map( )
number.map
Since number is an array, therefore
[ ].map( ) -> It's used to transform an array
The entire structure of the code has changed using Array.map( ) . The programmer doesn't have to bother about the loops. A loop signifies imperative control structure. A loop keeps changing the code. However, the crux of functional programming is immutability or statelessness, where the probability of breaking the global state is minimal.
The previous code could be written using the Lambda functions or Arrow functions as per ES6 JS.
num => Math.pow(num, 3)
is similar to
function num( ) {
return Math.pow(num,3)
}
Thanks for reading.
