I am looking to extract an array of values associated with a specific key from a collection of objects within an array using JavaScript.
Here is the parent array:
const data = [
{employeeId: 033, field: "TAX", active: 1},
{employeeId: 035, field: "ACCOUNTING", active: 1},
{employeeId: 035, field: "SALES", active: 1}
];
The desired output (an array of values for the key named 'field'):
["TAX", "ACCOUNTING", "SALES"]
If you want to extract specific values from an array in JavaScript, you can utilize the Array#map method.
const data =[{employeeId: 033, field: "TAX", active: 1},
{employeeId: 035, field: "ACCOUNTING", active: 1},
{employeeId: 035, field: "SALES", active: 1}];
const result = data.map(item => item.field);
// alternatively, you can use a.map(({field})=>field);
console.log(result);Utilizing array.map can help streamline the process of transforming an array.
const data =[{employeeId: 033, field: "TAX", active: 1},
{employeeId: 035, field: "ACCOUNTING", active: 1},
{employeeId: 035, field: "SALES", active: 1}];
console.log(data.map((entry) => entry.field));Looking for help with a function that can determine if a string contains a period and add one if it doesn't. So far, I'm struggling to make it either continuously add periods or not add any at all. function checkPeriod() { if (inputString.indexO ...
