How can I iterate over dictionary of objects in TypeScript?
I have map of object like this:
let dictionary = {
'key1' : {
id : 47,
name : 'Test 1'
},
'key2' : {
id : 51,
name : 'Test 2'
},
'key3' : {
id : 141,
name : 'Test 3'
},
};
What is the best and recommended way of doing that?
Quick solution:
for(let key in dictionary) {
let value = dictionary[key];
let id = value.id;
let name = value.name;
}We can use any other property defined under dictionary value, by using value.propertyName.
We can use standrad for...in loop over object from JavaScript, code example:
// ONLINE-RUNNER:browser;
let dictionary = {
'key1' : {
id : 47,
name : 'Test 1'
},
'key2' : {
id : 51,
name : 'Test 2'
},
'key3' : {
id : 141,
name : 'Test 3'
},
};
for(let key in dictionary) {
let value = dictionary[key];
let id = value.id;
let name = value.name;
console.log('key: ' + key + ', id: ' + id + ', name: ' + name);
}You can take a look at article, point 3 (3. for...in loop over object example)
