Can you identify which code block does not contain a syntax error? Out of the 4 options below, one of them is free from any syntax mistakes.
alert("hello "+3+" times);
alert("hello "+3 times);
alert("hello +3+ times");
alert("hello "+3 +" times);
The third option is the correct one because it uses paired quotes around the strings. You can test it by using this code snippet:
alert("hello +3+ times");
Experiment with individual testing like below in your script to see how it behaves:
alert("hello "+1+" times);
alert("hello "+2 times);
alert("hello +3+ times");
alert("hello "+4 +" times);
alert("hello "+5+" times");
alert("hello " + 6 + " times");
console.log("Greetings " +3+ " times"); // closing doublequote missing
console.log("Greetings "+3 times); // both doublequotes are missing around strings
console.log("Greetings +3+ times"); // there is no syntax error, it will alert the string literal
console.log("Greetings "+3 +" times"); // lacking the closings doublequotes
