JavaScript : unhelpful error messages, assertSimilar is deprecated, needs Node.js upgrade

No random test in Python.

• Node 18. should be enabled

• assert.deepEqual should be used

The rust version has no random tests.

From the description :

The Rust implementation should return an ordered BTreeMap. Letters with the same frequency are ordered alphabetically. For example:

The Rust implementation expects letters in alphabetic order, regardless of frequency.
From the test suite :

    let answer: BTreeMap<char, i32> =
    [('a', 4),
     ('d', 1),
     ('f', 2),
     ('s', 2),
     ('x', 3)]
     .iter().cloned().collect();

The order, according to my interpretation of the description, should be a, x, f, s, d.

Typescript and Julia translations.

No random tests.
