Commas & Semicolons Back

1. Commas

• Add one space after each commas.
• It's recommended that adding commas of each properties, buy I'm familiar with the style that last property does not have the commas.
• Eslint rules tags: comma-dangle

/** bad */
const items = [1,2,3];

/** good */
const items = [1, 2, 3];

/** recommended */
const items = [
    1,
    2,
    3,
];

/** bad */
const obj = {
    name: 'Aleen',
    age: '22'
};

/** recommended */
const obj = {
    name: 'Aleen',
    age: '22',
};

2. Semicolons

• Add semicolons after each statements.
• Eslint rules tags: semi

/** bad */
const i = 1

/** good */
const i = 1;
