Javascript: Find The Closest Number In Array To A Specific Value
var array = [];
function closest(array,num){
var i=0;
var minDiff=1000;
var ans;
for(i in array){
var m=Math.abs(num-array[i]);
if(m<minDiff){
minDiff=m;
ans=array[i];
}
}
return ans;
}
/*call array name and desired value to be closet */
alert(closest(array,88));

I came up with this ...
const nearest = (arr) => val => arr.reduce((p,n) => Math.abs(p) > Math.abs(n-val) ? n-val : p, Infinity) + val;

let num = 5;
let arr =[1,2,3,4,5,6,7,8,9,10];
const result = arr.reduce((prev, curr) => Math.abs(curr - num) < Math.abs(prev - num) ? curr : prev);
