I want to use values from "property: []" sub-array inside the "name: id" section but it gives
"Cannot read property 'property' of undefined" error. How can I prevent the error and solve this?
Basically I want to push datas inside the subarray than use it inside the main array how can I do that?
function generateObject(id, Samplelist) {
Object[id] = {
name: Object[id].property[0],
property: []
};
Samplelist.forEach((list, i) => {
Object[id].property.push({
type: types[order[i]],
quality: qual[fileToMap],
});
});
}You can not assign something before initializing it. First create the object, populate the property and then use it to assign other properties.
function generateObject(id, lists) {
Object[id] = {
name: undefined, // you can not existact somethng before adding it
property: []
};
Samplelist.forEach((list, i) => {
Object[id].property.push({
type: types[order[i]],
quality: qual[fileToMap],
});
});
// after property is assinged value in foreach you can proceed to assign it
Object[id].name = Object[id].property[0];
}
