Note: Just because the expression evaluated to false, that does not mean that x is greater than y. With this change, if the expression for the condition ( x > y) is evaluated to be false, “x is not greater than y” will be printed to the console. In the example above, an else statement was added. If (x > y) console.log('x is greater than y')Įlse console.log('x is not greater than y') The example below demonstrates how to augment an if statement with an else clause: let x = 7 If you wish to execute a code in the event that a condition is not met, use else. In the above example code, if the expression ( x > y) is false nothing happens. Note: The expression of the condition has to be something that can be evaluated to either true or false. Note: In most cases, if statements require the use of comparison operators, or l ogical operators, or both. The full syntax is covered below under Syntax. Note: the example above uses the short syntax. In simple words, the action taken is as follows: if x is greater than y, print “x is greater than y” to the console.Īll if statements follow the same general logic: if an expression is true ( a condition is met) then execute the provided code. The example then makes a choice based on comparing the two values with the greater than operator ( >). x is given the value of 7, and y is given the value of 5. The above example defines two variables – x and y. If (x > y) console.log('x is greater than y')

Basic if statement exampleīelow is a basic example of an if statement: let x = 7 This article will explore the if statement in detail. if statements (including else if and else).JavaScript has three types of conditional statements: Conditional statements are used to execute specified actions only if a provided condition (or set of conditions) is met.

An if statement is a conditional statement, as the name implies.Ĭonditional statements are used very often in code.
