America finally decided after more than three days of uncertainty while election ballots were counted.

In his first speech since being named US president-elect, Joe Biden promised to "unify" the country and heal deep divisions. But what more do we know about the 77-year-old, who, after his inauguration on 20 January, will officially become the next US commander-in-chief?

When he formally announced his entry into the 2020 presidential race, Joe Biden declared that he stood for two things - workers who "built this country", and values that can bridge its divisions.

As the US faces challenges from coronavirus to racial inequity, his pitch is to create new economic opportunities for workers, restore environmental protections and healthcare rights, and international alliances.

Approach to tackling coronavirus

Mr. Biden, who has served in public life for around a half-century, is emphasizing his government experience, seeking to cast himself as a steady, seasoned hand in a dangerous and uncertain world.

As the coronavirus crisis has unfolded, he has looked for ways to help voters picture him as commander in chief, formulating recommendations rooted in advice from health care and economics experts.

Mr Biden's approach to tackling coronavirus is to provide free testing for all and hire 100,000 people to set up a national contact-tracing programme.

Mr Biden plans to establish at least 10 testing centres in every state, call upon federal agencies to deploy resources and give firmer national guidance through federal experts. He says all governors should mandate wearing masks.

To address the immediate impact of the coronavirus crisis, Mr Biden has vowed to spend "whatever it takes" to extend loans to small businesses and increase direct money payments to families.

Criminal Justice reform

In the wake of the race protests that have gripped the US this year, he said he believes that racism exists in the US and must be dealt with through broad economic and social programmes to support minorities. A pillar of his "build back" programme is to create business support for minorities through a $30bn investment fund.

Global climate change

Mr Biden has called climate change an existential threat, and says he will rally the rest of the world to act more quickly on curbing emissions by rejoining the Paris Climate Accord. The agreement, which Donald Trump withdrew from, committed the US to cutting greenhouse gases up to 28% by 2025, based on 2005 levels.

Undo Trump’s policies

In his first 100 days in office, Mr Biden promises to reverse Trump policies that separate parents from their children at the US-Mexican border, rescind limits on the number of applications for asylum and end the bans on travel from several majority-Muslim countries. He also promises to protect the "Dreamers" - people brought illegally to the US as children who were permitted to stay under an Obama-era policy - as well as ensure they are eligible for federal student aid
