JavaScript Statements

In JavaScript, statements are individual instructions that are executed sequentially to perform specific actions or operations. Here's an overview of some common types of JavaScript statements:

Example

        let a, b, c;    // Statement 1
        a = 4;          // Statement 2
        b = 5;          // Statement 3
        c = a + b;      // Statement 4

Variable Declaration:

Example

  var x; // Declaration
    var y = 5; // Declaration with initialization

Assignment:

Example

x = 10; // Assignment

Conditional Statements: if...else Statement:

Example

  if (condition) {
    // code to be executed if condition is true
} else {
    // code to be executed if condition is false
}

switch Statement:

Example

 switch (expression) {
    case value1:
        // code to be executed if expression === value1
        break;
    case value2:
        // code to be executed if expression === value2
        break;
    default:
        // code to be executed if expression doesn't match any case
}

Loops:for Loop:

Example

 for (initialization; condition; increment/decrement) {
    // code to be executed repeatedly
}

while Loop:

Example

while (condition) {
    // code to be executed as long as condition is true
}

do...while Loop:

Example

 do {
    // code to be executed at least once, then repeatedly if condition is true
} while (condition);

Function Declaration:

Example

function functionName(parameter1, parameter2) {
    // code to be executed
}

Return Statement::

Example

 return value; // Exits the function and returns a value

Break and Continue:

break Statement: Used to exit a loop or switch statement.
continue Statement: Used to skip the current iteration of a loop and continue with the next iteration.

Throw Statement:

Example

 throw 'Error message'; // Throws an error

Try...Catch Statement::

Example

 try {
    // code that might throw an error
} catch (error) {
    // code to handle the error
}
