An “else statement” in JavaScript is used in conjunction with an “if statement” to specify a block of code to be executed if the condition in the “if statement” is false. The basic syntax for an else statement is as follows:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
if (condition) {
// code to be executed if condition is true
} else {
// code to be executed if condition is false
}
[/dm_code_snippet]
It’s important to note that the “else” block of code will only be executed if the condition in the “if” statement is false.
Additionally, you can use “else if” statement to chain multiple conditions together. The basic syntax for an “else if” statement is as follows:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
if (condition1) {
// code to be executed if condition1 is true
} else if (condition2) {
// code to be executed if condition1 is false and condition2 is true
} else {
// code to be executed if both condition1 and condition2 are false
}
[/dm_code_snippet]
It’s also worth noting that JavaScript also supports the ternary operator as a shorthand for simple if-else statements. The ternary operator has the following syntax:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
condition ? true : false;
[/dm_code_snippet]
The code above will check the condition and return the value of true if the condition is true, and false if the condition is false.
