1It just checks the array,
2for the condition you gave,
3if atleast one element in the array passes the condition
4then it returns true
5else it returns false

1['one', 'two'].some(item => item === 'one') // true
2['one', 'two'].some(item => item === 'three') // false

5// Some returns a boolean value.
6Object.values(obj).some((item) => {
7	// Loop breaks as soon as the condition has been met.
8  	// Getting your value, can be used like:
