Is it possible to use this library to load jinja2 yaml templates?

[syllogismos]

I have a jinja2 yaml template and I want to be able to parse it using js-yaml.

Something like plugin system for ruamel.yaml from this answerl https://stackoverflow.com/a/44515747

On python you can do something like below after installing the jinja2 plugin for ruamel.yaml

import os
from ruamel.yaml import YAML


yaml = YAML(typ='jinja2')

with open('input.yaml') as fp:
    data = yaml.load(fp)

myArray = data['A']['B'][1]['myArray']
pos = myArray.index('val2')
myArray.insert(pos+1, 'val 3')

with open('output.yaml', 'w') as fp:
    yaml.dump(data, fp)

os.system('diff -u input.yaml output.yaml')

Is there any way to do this on javascript? I should be able to load a jinja2 yaml file, modify the yaml parts and dump it and still have the jinja2 templating variables/for loops and etc.
