Disallow Function Constructor (no-new-func)
It's possible to create functions in JavaScript using the Function
constructor, such as:
var x = new Function("a", "b", "return a + b");
This is considered by many to be a bad practice due to the difficulty in debugging and reading these types of functions.
Rule Details
This error is raised to highlight the use of a bad practice. By passing a string to the Function constructor, you are requiring the engine to parse that string much in the way it has to when you call the eval
function.
Examples of incorrect code for this rule:
/*eslint no-new-func: "error"*/
var x = new Function("a", "b", "return a + b");
var x = Function("a", "b", "return a + b");
Examples of correct code for this rule:
/*eslint no-new-func: "error"*/
var x = function (a, b) {
return a + b;
};
When Not To Use It
In more advanced cases where you really need to use the Function
constructor.
