WHAT IS A STATEMENT

EXCEPT FUNCTION IF NOTICE {curly braces} in code its likey a statement

A for loop that logs numbers 0 to 4.

for (let i = 0; i < 5; i++) {
   console.log (1) ;
}
  • A while loop that decrements x and logs it until x is no longer greater than 0.
let x = 5
while (x > 0) {
  x—-;
  console.log (x);
}
  • Value assignment to variable
const x = -19; 
const color = 'blue'
  • An if...else statement that logs if x is positive or not.
if (x > 0) {
  console. log("x is positive");
} else 1
  console. log("x is zero or negative");
}
  • A switch statement that handles different color cases.
switch (color) {
  case "red":
      console.log ("Color is red");
  break;

  case "blue":
      console. log ("Color is blue"); 
  break;

  default:
      console. log ("Color is not red or blue");
}
  • A try...catch block that handles errors from riskyFunction.
try {
  let result = riskyFunction();
} catch (error) {
  console.error(error);
}

throw new Error ("Something went wrong"); // Throws a new error with a message.

WHAT IS AN EXPRESSION

Expression is a code which evaluates to a value
  • Literal expressions
42; // The number 42 is a literal expression.
"Hello"; // The string "Hello" is a literal expression.
  • Arithmetic expressions
5 + 3; // Evaluates to 8.
x * y; // Evaluates to the product of x and y.
  • Logical expressions
true && false; // Evaluates to false.
x || y; // Evaluates to x if x is true, otherwise y.
  • Function expressions
const funcExpr = function() & return 42; 3; // Defines a function expression.
const arrowFunc = () => 42; // Defines an arrow function expression.
  • Object and array initializers
const objectInitializer = { name: "John", age: 30}: // Object initializer expression.
const objectInitializer = [11, 2, 31]; // Array initializer expression.
  • Property access expressions
obj.name; // Accesses the "name" property of 
obj.array[0]; // Accesses the first element of array.
  • Function calls
square(7); // Evaluates to 49.
Math.max(4, 3, 2); // Evaluates to 4;
