I was ask a question in an interview to convert a string number to a number.
eg : My string is "TEN" . and I have to convert it to number 10.
Please help.
Thanks
if (string === "TEN") value = 10;
I think you misunderstood the interviewer's question. He meant getting the number that is currently in a string, not getting the number that is currently spelled out in a string.

I wanna get number of total array in NodeJS. Any way can do this?
For example: In picture have array from 0 > 558. Then I want a function to give the count is 559
Thank you.
Hieu
The array is only broken in console since it is very long: (i.e: if the length of array is longer than 100 then the console will break it to show it clearly..). if u logged the length then it will show 559, just do arr.length

What is the difference between a Number and Integer in Javascript. This is an edit after the answer - I thought that the Integer datatype exists because of the function parseInt.
There is no Integer type in JavaScript; it treats ints and floats the same way

If I have a string in this format:
RED-MPWMC-40486655646-024
How can I extract MPWMC from this string with javascript?
No need of regex here. Just split it using - and access the array element with index=1.
var str = "RED-MPWMC-40486655646-024";
console.log(str.split("-")[1]);

I want to split strings by commas and dots using javascript. For example, a string of "10,256,326.26" would turn into ["10", "256", "326", "26"] after getting split.
Which regex can I use for this?
You can use a character class containing all characters on which you want to split
var s = "10.269,69";
document.write(s.split(/[,.]/))
You can use split() with a regex:
console.log(str.split(/,|\./));
