My object look something like this.
var fruits = [
{
name: 'apple',
color: 'golden'
},
{
name: 'pear',
color: 'green'
},
{
name: 'mango',
color: 'yellow'
}
]
Now what i want is an array of the names of the fruit from the fruit object
console.log(getFruitNames(fruits)) //['apple','pear','mango']
You only need a map to return each name.
var fruits = [
{
name: 'apple',
color: 'golden'
},
{
name: 'pear',
color: 'green'
},
{
name: 'mango',
color: 'yellow'
}
]
console.log(getFruitNames(fruits))
function getFruitNames(fruits){
return fruits.map(m => m.name)
}Also a TS playgorund
Array.prototype.map() is what you need.
It will create a new array populated with the results of calling the provided function on every element in the calling array.
var fruits = [
{
name: 'apple',
color: 'golden'
},
{
name: 'pear',
color: 'green'
},
{
name: 'mango',
color: 'yellow'
}
];
console.log(fruits.map(x => x.name))more about map can be found here : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map
