unicorn/prefer-code-point Pedantic
What it does
Prefers usage of String.prototype.codePointAt
over String.prototype.charCodeAt
. Prefers usage of String.fromCodePoint
over String.fromCharCode
.
Why is this bad?
Unicode is better supported in String#codePointAt()
and String.fromCodePoint()
.
Difference between String.fromCodePoint()
and String.fromCharCode()
