JavaScript is one of the favorite programming languages that is mainly used for web development. Statements in JavaScript allow you to execute your commands based on certain conditions. These statements can include defining variables, executing loops, and performing functions. Overall, JavaScript statements aim to facilitate the management of program flow and data handling.
One of the interesting features of JavaScript is its simplicity and high readability, which allows all developers to easily understand it through clear and comprehensible statements. Hence, mastering JavaScript and utilizing its statements can assist you in coding more complex and functional programs.
Conditional statements are among the most commonly used types of statements that allow you to execute specific commands based on certain conditions. "if" and "switch" are among the most popular conditional statements in JavaScript.
Loop statements such as "for", "while", and "do...while" provide you the ability to repeat specific commands, running them multiple times when needed. This process allows you to process collections of elements or perform repetitive actions efficiently.
Similarly, statements in JavaScript include key elements such as "let", "const", and "function" that can help you define variables, constants, and functions, providing better control over your code.
let x = 10;
if (x > 5) {
console.log("x is greater than 5");
}
for (let i = 0; i < 5; i++) {
console.log(i);
}
let x = 10; → In this line, a variable named x is initialized with a value of 10.
if (x > 5) → This line checks whether the value of x is greater than 5 or not.
{ and } → These define the block of code to be executed if the condition is true.
console.log("x is greater than 5"); → If the condition is met, this line will print "x is greater than 5" to the console.
for (let i = 0; i < 5; i++) → This starts a loop that will iterate the value of i from 0 to 4.
console.log(i); → This line outputs the current value of i to the console during each iteration.
