Here's a snippet of my JSON object (EDITED) -
[{
"traditional": "%",
"simplified": "%",
"referencedTraditional": [],
"referencedSimplified": [],
"pinyinNumeric": "pa1",
"pinyinDiacritic": "pā",
"definitions": [
"percent (Tw)"
],
"definitionsDiacritic": [
"percent (Tw)"
]
},
{
"traditional":"龠","simplified":"龠","referencedTraditional":[{"cp":"9fa0","c":"龠"}],"referencedSimplified":[{"cp":"9fa0","c":"龠"}],"pinyinNumeric":"yue4","pinyinDiacritic":"yuè","definitions":["ancient unit of volume (half a 合[ge3], equivalent to 50ml)","ancient flute"],"definitionsDiacritic":["ancient unit of volume (half a 合[gě], equivalent to 50ml)","ancient flute"]},
{"traditional":"龡","simplified":"龡","referencedTraditional":[{"cp":"9fa1","c":"龡"}],"referencedSimplified":[{"cp":"9fa1","c":"龡"}],"pinyinNumeric":"chui4","pinyinDiacritic":"chuì","definitions":["to blow (a flute)","archaic version of 吹"],"definitionsDiacritic":["to blow (a flute)","archaic version of 吹"]},
]
I want to convert every key called definitions from an array into a string.
E.g. From ["percent (Tw)"] to "percent (Tw)". Basically, I don't want the array brackets.
So far, I've tried looping through the file and converting every "definitions" key with JSON.stringify() or toString() -
translations.forEach(key => JSON.stringify((key.definitions)))
However, nothing changes in the outputted file.
Issue with the code is the one below
translations.forEach(key => JSON.stringify((key.definitions)))
Simply running this statement will not update the value for the key inside that object. You have to update the object for this.
Logic.
translations. I used Object.entries(translations).forEach for that."definitions" in that key."definitions" in that, run your stringification logic. I prefer Array.join() compared to JSON.stringify.Working Fiddle
const translations = {
"traditional": "%",
"simplified": "%",
"referencedTraditional": [],
"referencedSimplified": [],
"pinyinNumeric": "pa1",
"pinyinDiacritic": "pā",
"definitions": [
"percent (Tw)"
],
"definitionsDiacritic": [
"percent (Tw)"
]
}
Object.entries(translations).forEach(([key, value]) => key.includes('definitions') ? translations[key] = translations[key].join("") : null);
console.log(translations);const obj = {
traditional: '%',
simplified: '%',
referencedTraditional: [],
referencedSimplified: [],
pinyinNumeric: 'pa1',
pinyinDiacritic: 'pā',
definitions: ['percent (Tw)'],
definitionsDiacritic: ['percent (Tw)'],
};
const returnStringDefinitions = (obj) => {
const arr = [];
for (const [key, value] of Object.entries(obj)) {
if (key === 'definitions') arr.push(value.toString());
}
return arr;
};
console.log(returnStringDefinitions(obj));I think what may be happening for you is that you aren't saving the resulting array anywhere. The approach could be to create a new object.
const obj = {
traditional: '%',
simplified: '%',
referencedTraditional: [],
referencedSimplified: [],
pinyinNumeric: 'pa1',
pinyinDiacritic: 'pā',
definitions: ['percent (Tw)'],
definitionsDiacritic: ['percent (Tw)'],
};
const output = Object.keys(obj).reduce((accumulator, currentKey) => {
const currentValue = obj[currentKey];
if (currentKey === 'definitions' && Array.isArray(currentValue)) {
accumulator[currentKey] = currentValue.join('');
} else {
accumulator[currentKey] = currentValue;
}
return accumulator;
}, {})
console.log(output);
This solution checks if it is an array, and also just joins everything in the array just in case there are multiple things in the array, but how this is handled is really up to you :)
