Based on the spec for YAML 1.2, underscores shouldn't be allowed in numbers:
https://yaml.org/spec/1.2/2009-07-21/spec.html#id2604185
However the latest js-yaml still allows them:
package.json
{
"dependencies": {
"js-yaml": "^4.1.0"
}
}
test.js
const yaml = require('js-yaml');
const data = yaml.load(`
string: '1_2_3'
also_string: 1_2_3
`);
console.log(typeof data.string);
console.log(typeof data.also_string);
$ node test.js
string
number
Is this intended behaviour? Thanks in advance.
