JavaScript is a high-level programming language used primarily for developing web applications. Here is an overview of its features, code blocks, and resources.
Variables are used to store data that can be used later in the program.
let variableName = value;
Functions are code blocks that perform a specific task. They can be called by other parts of the program.
function functionName(parameter1, parameter2) {
// code to be executed
}
Conditionals allow the program to make decisions based on certain conditions.
if (condition) {
// code to be executed if condition is true
} else if (otherCondition) {
// code to be executed if otherCondition is true
} else {
// code to be executed if neither condition is true
}
Loops allow the program to repeat a set of instructions.
for (let i = 0; i < 10; i++) {
// code to be executed
}
Objects are a fundamental part of JavaScript and are used to store and manipulate data.
const objectName = {
property1: value1,
property2: value2,
method: function() {
// code to be executed
}
};
