For example, let num = 4; // if condition if (num % 2 == 0) console.log("even number"); else console.log("odd number"); // Output: even number Run Code JavaScript else if StatementWe can use the else if keyword to check for multiple conditions.The syntax of the else if ...
When assigning a variable value to another variable, you may want to make sure that the source variable is not null, undefined, or empty. You can write long if statements with multiple conditions, or you can use short-circuit evaluation. // Longhand if (name !== null || name !== und...
if (value < 5) { //do something } else if (value > 5 && value < 10) { //do something } else { //do something } This code is optimal only if value is most frequently less than 5. If value is typically greater than or equal to 10, then two conditions must be evaluated each...
If blocks can also simultaneously evaluate multiple different expressions. If you want one clause to check two or more conditions, you need to combine these conditions using logical operators. We’ll show you how to use three of them – the AND operator (“&&”), the OR operator (“||”...
The above example uses the%operator, which returns the remainder when the number preceding it is divided by the number following it. If the remainder when divided by2is0, the number is even. Example: Filtering Strings Using Multiple Conditions ...

Enter the conditions and actions in a series of control flow statements. Compare the conditions that are listed above to see how they are translated into JavaScript: if (issueFields.becomes(ctx.State, ctx.State.Fixed)) { setPhase(ctx.Phase.Testing); } else if (issueFields.becomes(ctx.State...
Else if Statement Withifandelse, we can run blocks of code depending on whether a condition istrueorfalse. However, sometimes we might have multiple possible conditions and outputs, and need more than simply two options. One way to do this is with theelse ifstatement, which can evaluate mor...
