Script Preparation code:

var values = [];
for (let i = 0; i < 10000; ++i) {
  values.push(i);
}

Tests:

map, join
let result1 = values.map(v => `x = ${v}`).join(' or ');
forEach, addition assignment
let result2 = '0=1'; values.forEach(v => result2 += ` or x = ${v}`);
reduce, template literal
const result3 = values.reduce((a,v)=> `${a} or x = ${v}`, '0=1');
