A linting utility with a built-in set of code-style rules for JS, TS, and CSS

• Install codeshape into a project: npm i -D codeshape (or globally: npm i -g codeshape);
• Run codeshape in the project directory.

As in the mathematical notation of vectors and set elements: (x, y, z), {x, y, z}.

[x, y, z]
{x, y, z}
{x: 0, y: 1, z: -1}

import {x} from './x';

else and catch on the next line after } allow for consistent placement of comments covering the condition and the entire following block:

// this is a comment to the condition
if (condition) {
    // ...
}
// another comment
else if (otherCondition) {
    // ...
}
// yet another comment
else {
    // ...
}

As in the mathematical notation.

function(params), setCustomValue(value) as in f(x), no space before the bracket.

if (x), for (let i...), while (ok) as in regular logical statements, with a space before the conditional expression.

let f = x => x + 10; — akin to mapping a scalar x, normally unbracketed.

let g = (x, y) => x + y - 10; — akin to mapping a vector (x, y), normally bracketed.

Motivation:

• Simple decision making, reduced cognitive load: let is good for all variables, let is the default;
• Adherence to the semantic meaning of constants: const is an option to emphasize and communicate to other developers that a certain value should not be reassigned, which applies to intentionally fixed values and normally doesn't semantically apply to one-time local variables;
• Compliance to the definition: const is for values that can't be reassigned, rather than for values that are not reassigned.
