This is my post id:
var postId = 47213486358396931;
var postComments = "Comment";
adding in object like this
var param = {
"PostId" : postId,
"postComment":postComments
}
If I print the param I get like this. The last digit of number changed to 0. Why am getting like this.
{"PostId" : 47213486358396930, "postComment": "Comment"}

I need to read the numeric value of one line in a text file
color=7
so var color will = 7
Split the string by '=', get the second value and turn it into an int:
let data = 'color=7';
let color = parseInt(data.split('=')[1]);
console.log(color);
Do note that if the value after the = isn't a number in this case, the code will throw an excpetion so you might wanna catch it.
