Imagine we have an object that contains information about fruit quantities in different batches:
"fruit_quantities" : {
"batch1": {
mango : 100,
apple: 50
},
"batch2": {
mango : 0,
apple: 50
},
"batch3": {
mango : 0,
apple: 50
}
}
I am interested in checking if the value of mango is greater than 0, regardless of the batch it is in. How can I achieve this using JavaScript?
To achieve this, you can utilize the power of Object.keys() in combination with the Array.prototype.some() method as shown below:
var fruit_quantities = {
"batch1": {
mango : 100,
apple: 50
},
"batch2": {
mango : 0,
apple: 50
},
"batch3": {
mango : 0,
apple: 50
}
};
var fruit = "mango";
var r = Object.keys(fruit_quantities).some(function(key) {
return fruit_quantities[key][fruit] > 0;
});
console.log(r);When working in R, you have the ability to create functions that can handle unquoted attributes of a pre-defined object as arguments. For instance, the DataFrame object interface allows for operations like: # df has columns "A" and "B" df = mutate(df, C=A ...
