Question
Which of the following is a correct way to write an if statement in JavaScript?
if (x === 5) {}
if x = 5 then {}
if x == 5 {}
if x === 5: {}
Solution
The correct way to write an if statement in JavaScript from the given options is:
if (x === 5) {}
Explanation
- The first option uses the correct syntax of an if statement in JavaScript, which requires parentheses around the condition and curly braces for the block of code to execute if the condition is true.
- The second option, "if x = 5 then {}", uses assignment (
=
) instead of comparison (===
or==
), and also incorrectly uses "then". - The third option, "if x == 5 {}", misses the necessary parentheses around the condition.
- The fourth option, "if x === 5: {}", incorrectly uses a colon instead of curly braces.
Final Answer
if (x === 5) {} is the correct way to write an if statement in JavaScript.
