noWith (since v12.0.0)
Disallow with statements in non-strict contexts.
The with statement is potentially problematic because it adds members of an object to the current scope, making it impossible to tell what a variable inside the block actually refers to.
Examples
Invalid
function f() {
with (point) {
r = Math.sqrt(x * x + y * y); // is r a member of point?
}
