How does yamljs.load work?

yamljs.load is a function provided by the yamljs library that parses a YAML string into a JavaScript object or array. It takes a string as input and returns a JavaScript object or array, depending on the input YAML. The function supports most of the YAML 1.2 specification, including support for anchors and aliases, and can handle complex data structures such as nested objects and arrays. The resulting JavaScript object or array can then be used by the application to manipulate and work with the data in a structured way.

const yaml = require("yamljs");

const yamlString = `
name: John
age: 30
hobbies:
- reading
- writing
`;

const parsedYaml = yaml.load(yamlString);
console.log(parsedYaml);
// Output: { name: 'John', age: 30, hobbies: [ 'reading', 'writing' ] }

In this example, the yaml.load() function is used to parse a YAML string and convert it into a JavaScript object. The resulting object is then logged to the console.
