I have some javascript where I’m trying to create a promotion
within each of my promotion items. Right now though, for some reason it keeps on nesting itself indefinitely, and I only need it to contain one reference (see screenshot)
I’ve tried adding a check to see if promotion.promotion
already exists and if it does to continue, but this just doesn’t seem to run.
What am I missing?
const promotions = [{ title: 'My offer title', subtitle: 'lorem ipsum' }, { title: 'My offer title 2', subtitle: 'lorem ipsum' }, { title: 'My offer title 3', subtitle: 'lorem ipsum' }] for (const [index, promotion] of promotions.entries()) { if (promotion.promotion) continue promotion['promotion'] = promotion }
Here’s a jsfiddle for a demo.
This is what I need for the output:
const promotions = [{ title: 'My offer title', subtitle: 'lorem ipsum', promotion: { title: 'My offer title', subtitle: 'lorem ipsum', } }, { title: 'My offer title 2', subtitle: 'lorem ipsum', promotion: { title: 'My offer title 2', subtitle: 'lorem ipsum', } }, { title: 'My offer title 3', subtitle: 'lorem ipsum', promotion: { title: 'My offer title 3', subtitle: 'lorem ipsum', } }]

for (const [index, promotion] of promotions.entries()) { if (promotion.promotion) continue promotion.promotion = { ...promotion} }
