Javascript Conditional Operators

Introduction to Conditional Operators

Conditional operators in JavaScript are essential for decision-making in code. They allow for executing different actions based on varying conditions.

The if Statement

The if statement is the most fundamental conditional operator, used to execute a block of code only if a specified condition is true.

Syntax:

if (condition) {
  // code to execute if condition is true
}

Example:

The else Statement

The else statement complements the if statement, allowing for code execution when the if condition is false.

Syntax:

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

Example:

The else if Statement

else if allows for multiple conditions to be tested in sequence.

Syntax:

if (condition1) {
  // code if condition1 is true
} else if (condition2) {
  // code if condition2 is true
} else {
  // code if neither condition is true
}

Example:

The Conditional (Ternary) Operator ?

The ternary operator is a shorthand for the if...else statement, useful for assigning values based on a condition.

Syntax:

let result = (condition) ? value1 : value2;

Example:

Conclusion

Mastering conditional operators in JavaScript is crucial for creating dynamic and responsive code. These operators enable the script to make decisions and react differently under varying conditions.
