Description
JavaScript's eval() function is potentially dangerous and is often misused.
Using eval() on untrusted code can open a program up to several different injection attacks.
The use of eval() in most contexts can be substituted for a better, alternative approach to the problem.
Bad Practice
const obj = { x: "foo" }
const key = "x"
const value = eval("obj." + key);
(0, eval)("var a = 0");
const foo = eval;
foo("var a = 0");
// This `this` is the global object.
this.eval("var a = 0");
Recommended
const obj = { x: "foo" },
key = "x",
value = obj[key];
class A {
foo() {
// This is a user-defined method.
this.eval("var a = 0");
}
eval() { /* ... * / }
}
