What are JavaScript Statements?<\/strong><\/h2>\n\n\n\n

JavaScript\u00a0statements\u00a0are\u00a0commands\u00a0that\u00a0tells\u00a0the\u00a0browser\u00a0what\u00a0to\u00a0do.\u00a0They\u00a0are\u00a0the\u00a0building\u00a0blocks\u00a0of\u00a0JavaScript\u00a0code\u00a0and\u00a0are\u00a0executed\u00a0in\u00a0the\u00a0order\u00a0they\u00a0are\u00a0written. Statements often\u00a0end\u00a0with\u00a0a\u00a0semicolon\u00a0(;<\/code>),\u00a0although\u00a0it’s\u00a0not\u00a0always\u00a0mandatory.<\/p>\n\n\n\n

Assigment Statement<\/strong><\/h2>\n\n\n\n

An assignment statement assigns a value to a variable.<\/p>\n\n\n\n

let x = 10;<\/pre><\/div>\n\n\n\n
Function Call Statement<\/strong><\/h2>\n\n\n\n
A function call statement invokes a function.<\/p>\n\n\n\n
alert("Hello, World!");<\/pre><\/div>\n\n\n\n
Conditional Statement<\/strong><\/h2>\n\n\n\n
A conditional statement executes code based on a condition.<\/p>\n\n\n\n
if (x > 5) {\n    console.log("x is greater than 5");\n}<\/pre><\/div>\n\n\n\n
Loop Statement<\/strong><\/h2>\n\n\n\n
A loop statement repeats a block of code as long as a specified condition is true.<\/p>\n\n\n\n
for (let i = 0; i < 5; i++) {\n    console.log("Number " + i);\n}<\/pre><\/div>\n\n\n\n
JavaScript Code Blocks<\/strong><\/h2>\n\n\n\n
A code block is a group of statements enclosed in curly braces {}<\/code>. It is often used with control structures like if<\/code> statements and loops to execute multiple statements.<\/p>\n\n\n\n
{\n    let x = 10;\n    let y = 20;\n    let sum = x + y;\n    console.log("The sum is " + sum);\n}<\/pre><\/div>\n\n\n\n
