charAt

> Functions

TypeScript

In JavaScript, s.charAt(index) returns the empty string "" out of bounds, where charAt in LeekScript returns null: test === "", not === null. Two related forms: s[index] gives undefined out of bounds, and s.at(index) accepts a negative index counted from the end — "abc".at(-1) is "c", while "abc".charAt(-1) is "" and "abc"[-1] is undefined.

Python

In Python, you index the string directly: s[index]. An out-of-bounds index raises an IndexError instead of returning null like charAt in LeekScript, and a negative index counts from the end — "abc"[-1] is "c", not an error. To never raise an error, take a one-character slice: "abc"[5:6] is "".

Examples

charAt("Bonjour", 3) // "j" charAt("Bonjour", 999) // null
