Which of the following statements in JS will always produce an error?CHOOSE AS MANY ANSWERS AS APPLYGroup of answer choiceslet greyElephant23 = 10let GREYELEPHANT23 = 20greyElephant23 = 30grey-elephant23 = 40greyElephant23 = 50
Solution
The statement that will always produce an error in JavaScript is:
grey-elephant23 = 40
In JavaScript, variable names cannot contain hyphens. They can only contain letters, numbers, dollar signs, and underscores. Also, they cannot start with a number. Therefore, "grey-elephant23" is not a valid variable name and will produce an error.
