First, you will have to write a function that will iterate the subjectDetails<\/code> array and find the subject name based on a label.<\/p>\n

let subjectDetails = [{\n  \"subjectLabels\": {\n    \"eng\": \"english\",\n    \"sci\": \"environment science\",\n    \"soc\": \"History & Geo\"\n  }\n}]\n\nconst getSubjectName = (label) => {\n  let name = label;\n  \n  subjectDetails.forEach(details => {\n     if(details.subjectLabels.hasOwnProperty(label)){\n       name = details.subjectLabels[label]\n     }\n  })\n\n  return name\n}\n\nconsole.log(getSubjectName(\"eng\"))\n\/\/OUTPUT: english\n<\/code><\/pre>\n
The getSubjectName<\/code> will return the name of the subject if exists otherwise the default label.<\/p>\n
The second part is already answered on the referenced answer. All you have to do is to update the label in place.<\/p>\n<\/p>\n
