Passing in dynamic key:value pairs to an object literal? [duplicate]

Solution 1:

EDIT: Use var obj = {}; obj[key] = chunks[i];

Because ECMAScript treats the key in this {key:1} as literal.

Solution 2:

ES2015 (via Babel) Supports dynamic keys:

const Parameters=[];
const len = chunks.length;
for (let i = 0; i < len; i++) {
    const key = `key_${i}`;
    obj = { [key] : chunks[i]};
    Parameters.push(obj);
}

(note the brackets around the key)

Or better yet:

const Parameters = chunks.map((c, i) => ({ [`key_${i}`]: c }));
