autofixable

nommon/no-dynamic-jpath disallow JS variables in no.jpath().

Motivation: no.jpath(<jpath>) compiles given jpath to native JS function and stores it in cache. Dynamic jpath may increase memory usage and decrease application performance due to jpath compilation. You should use only static strings in jpath.

Bad examples:

no.jpath('.foo.' + bar, data);

no.jpath(`.foo.${ bar }`, data);

no.jpath(`.foo{ .bar === "${ baz }"`, data);

Good examples:

no.jpath('.foo' + '.bar', data);

no.jpath('.foo[bar]', data, { bar });

no.jpath('.foo{ .bar === baz}', data, { baz });
