Border: a line that goes around the padding and content.
Margin: space outside the border, separating the element from other elements.
Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope during the compilation phase.
Variable and function declarations are hoisted to the top of their scope.
Only declarations are hoisted, not initializations.
Function declarations take precedence over variable declarations.
Example: console.log(myVar); var myVar = 10; // Output: undefined

Normal functions are defined using the function keyword, while arrow functions are defined using the => syntax.
Normal functions are hoisted, while arrow functions are not hoisted.
Arrow functions do not have their own 'this' keyword, they inherit it from the parent scope.
Arrow functions do not have their own 'arguments' object.
Arrow functions are more concise and have implicit return.
Arrow functions cannot be used as co
Splice and slice are methods used in programming to manipulate arrays.
Splice is used to add or remove elements from an array at a specific index.
Slice is used to extract a portion of an array and returns a new array.
Example of splice: array.splice(2, 0, 'new element') - adds 'new element' at index 2.
Example of slice: array.slice(1, 4) - extracts elements from index 1 to 3.
Coding questions on Java script like array methods and objects handling. coding questions on React is like life cycle methods using functional components and state management.
