A handy function to convert your JS data to data tags.

datatagserialize.js

const dataTagSerialize = function(data) {
  if (typeof data === 'object') {
    if (Array.isArray(data)) {
      const elements = data.map(x => dataTagSerialize(x))
      return `[${elements.join(',')}]`
    } else {
      const keyValues = []
      for (let prop of Object.getOwnPropertyNames(data)) {
        keyValues.push([prop, dataTagSerialize(data[prop])])
      }
      const keyToValues = keyValues.map(e => `${e[0]}:${e[1]}`)
      return `{${keyToValues.join(',')}}`
    }
  } else if (typeof data === 'string') {
    const specialCharacters = ['\\','\"']
    let str = ''
    for (let i = 0; i < data.length; i++) {
      if (specialCharacters.includes(data[i])) {
        str += '\\' + data[i]
      } else {
        str += data[i]
      }
    }
    return `"${str}"`
  } else if (typeof data === 'number') {
    return parseFloat(data)
  } else if (typeof data === 'boolean') {
    return data
  }
