I have a meta as below:
obj = {
meta: [['type', 'test1'], ['key2', 'value2']],
value: 'text1',
}
Want to read value test by passing the key type
expected result is test1
You could use Object.fromEntries()
const obj = {
meta: [['type', 'test'], ['key2', 'value2']],
value: 'text1',
}
const key = 'type'
const res = Object.fromEntries(obj.meta)[key];
console.log(res)You should restructure meta as an object instead of an array of pairs as:
obj = {
meta: {
'type': 'test',
'key2': 'value2'
}
value: 'text1',
}
Now, you can access what you need as obj['meta']['type'] or obj.meta.type.
obj = {
meta: [['type', 'test'], ['key2', 'value2']],
value: 'text1',
}
for(let arr of obj.meta){
if(arr[0]==='type'){
return arr[1];
}
}
or
const res=obj.meta.find(arr=>arr[0]==="type");
if(res && res.length) return res[1]
Notice that this code returns only the first "type". If you have "type" twice you'll get the first result.
