Iterate over array of objects in Typescript
In Typescript and ES6 you can also use for..of:
for (var product of products) {
console.log(product.product_desc)
}
which will be transcoded to javascript:
for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
var product = products_1[_i];
console.log(product.product_desc);
}
You can use the built-in forEach
function for arrays.
Like this:
//this sets all product descriptions to a max length of 10 characters
data.products.forEach( (element) => {
element.product_desc = element.product_desc.substring(0,10);
});
Your version wasn't wrong though. It should look more like this:
for(let i=0; i<data.products.length; i++){
console.log(data.products[i].product_desc); //use i instead of 0
}
