Question
Problem statementSend feedbackWhich of the following 'for' loops would not produce any error?A) for(var i=0; i<5; ++i) { console.log("Hello") ; }B) var i , j ; for(i=0, j = 10; i < 10, j < 100) { console.log("Hello"); }C) var i ; for(i=0; i<5) { console.log("Hello"); }D) var i , j ; for(i=0, j=10; i<5; ++i) { console.log("Hello"); }Options: One or more answers may be correctABCD
Solution
The correct options are A, C, and D.
Option A is correct because it is a standard for loop in JavaScript. It initializes the variable i to 0, checks if i is less than 5, and increments i by 1 after each iteration.
Option B is incorrect because in JavaScript, the condition in a for loop should be a single expression that evaluates to a boolean value. The condition in this loop (i < 10, j < 100) is not a single expression.
Option C is correct because it is also a standard for loop in JavaScript. It initializes the variable i to 0, checks if i is less than 5, and increments i by 1 after each iteration.
Option D is correct because it is a standard for loop in JavaScript. It initializes the variables i and j to 0 and 10 respectively, checks if i is less than 5, and increments i by 1 after each iteration. The variable j is not used in the loop, but its presence does not cause an error.
