I am trying to get all the values in a JavaScript data table but whenever I try it says, "table.length is not a function" or, "table.size is not a function" (I've tried both).
Here is the code I want to use:
const wordcount = {"this", "is", "a", "data", "table"}
console.log(wordcount.size()) // wordcount.size is not a function
I want it to return an integer value to the console. How would I do this?
In the first line, Object's type is not true.
If you want to loop object, here is sample code.
// Object Loop
const wordcount = {
key1: "this",
key2: "is",
key3: "a",
key4: "data",
key5: "table"
}
for (let key in wordcount) {
console.log(wordcount[key])
}
Word count is not an valid array, see the code below it should work fine
const wordCount = ['this', 'is', 'a', 'data', 'table']
console.log(wordCount.length)
An array should always start with this '[' and end with this ']' not with '{'
I think I got your question wrong are you trying to make a data table? A data table must only contain primitive values such as string, number, Boolean, null, undefined etc.
// sample code
const data = {
name: "Jhon",
age: 25,
isChild: false,
}
Note: size is not a function it is an attribute
