eslint/no-inner-declarations Pedantic
What it does
Disallow variable or function declarations in nested blocks
Why is this bad?
A variable declaration is permitted anywhere a statement can go, even nested deeply inside other blocks. This is often undesirable due to variable hoisting, and moving declarations to the root of the program or function body can increase clarity. Note that block bindings (let, const) are not hoisted and therefore they are not affected by this rule.
Example
javascript
if (test) {
function doSomethingElse() {}
}How to use
To enable this rule in the CLI or using the config file, you can use:
bash
oxlint --deny no-inner-declarationsjson
{
"rules": {
"no-inner-declarations": "error"
}
}
