Script Preparation code:

const params = {
  'key[subKey1]': 'value1',
  'key[subKey2]': 'value2',
  'otherKey': 'otherValue',
  'key2[subKey3]': 'value3',
  'key2[subKey4]': 'value4',
};
const key = 'key2';

Tests:

string parser
const value = {} for (const paramKey in params) { if (paramKey.startsWith(`${key}[`) && paramKey.endsWith(']')) { const subKey = paramKey.substring(key.length + 1, paramKey.length - 1); value[subKey] = params[paramKey]; } }
regex parser
const value = {} for (const paramKey in params) { // regex: const match = paramKey.match(new RegExp(`^${key}\\[(.+)\\]$`)) if (match) { value[match[1]] = params[paramKey]; } }
