How To Get Nth Character In A String In Javascript?

I've a string (let's say 'Hello World') and I want to save the first characters of it in different variables (ex. character1 = 'H', character2 = 'e'...). How do I get the nth chara

Solution 1:

Let me summarize the possibilities

given:

varstring = "HAI";
/* and */var index = 1; // number ∈ [0..string.length), rounded down to integer

• string.charAt(index) returns "A" (preferred)
• string[index] returns "A" (non-standard)
• string.substring(index, index+1) returns "A" (over-complex solution but works)
• string.substr(index, 1) returns "A" (non-standard approach to above)

Solution 2:

Use the charAt method. As far as client or server, it depends on the context. But you should not trust client input.

Solution 3:

Not sure if this is cross-browser safe, but you can use array-like indexing:

"Hello"[0] ->"H"

The syntax is exactly the same in Python.
