How to check if subarray (within array) matches a value?-CodePudding

So i have some code that tries to detect if a block (on a canvas) is hitting another block by checking that current blocks x coordinates and seeing if it matches any other blocks x coordinates. The problem is, i cant use array.includes() because it will also check all of the y values too. The structure is someting like this:

array = [
[x, y],
[x, y],
]

etc...

is there any way to only check subarrays of that array?

CodePudding user response：

Check if .some of the subarrays have an item at the 1st index that's the same.

const collision = array.some(subarr => subarr[0] === xToCheck);
